- How to make phosphorescent glow in the dark powder. Also known as luminescent, photoluminescent or simply glow powder.
Warning: This experiment uses mildly toxic chemicals, wear gloves when handling them. In addition, the combustion reaction must be performed outside or in a fume-hood due to the resulting smoke and gasses.
For this experiment you'll need:
Strontium Nitrate: • Make Strontium Nitrate
Aluminum Nitrate: • How to Make Aluminum N...

And you'll need nitric acid to make the above nitrates: • Make Nitric Acid - The...
The procedure is relatively straightforward: 1.875g of aluminum nitrate nonahydrate with 530mg of strontium nitrate, 10.7mg of europium nitrate pentahydrate, 21.9mg of dysprosium nitrate pentahydrate and 30.9mg of boric acid are dissolved in 3mL of distilled water. 3.9g of pure urea is added and shaken until dissolved. The mixture is heated in a 1000watt microwave for 4 minutes. Eventually it'll ignite and combust. The white "ash" is the glow powder.
Can be used in Glow in the Dark Paint if crushed into a powder and mixed with an appropriate clear paint/resin/lacquer/glue.
I love how you're doing your own original chemistry and working towards a better product. Thanks for bringing us into your lab!
oh yes i agree, buying stuff is usually much cheaper than making it. But i made this video primarily to demonstrate the science and the process. I'm one of those weird people that's not content with simply having something, i want to know where it came from. :)
it came from a store of course :)
Can we extract the rare earth metals from the glow powder?
it would be grat if you made a video of how fosforecence works, i just saw the how flourecence works and it was great!
How long it glow ? Can u make something glow for long term
Don't forget "and how it works"
0:23 "How to make Glow Powder at home"
Ingredients that you have *"at home"* :
- Pure Aluminum Nitrate
- Pure Strontium Nitrate
- Europium Nitrate
- Dysprosium Nitrate
- Urea (Not Urine)
- And Boric Acid!
All chemicals are *"totally"* at your home and can easily be find at your local hardware store!
Lol
Lol 😆
@mikethomas2988 While this does produces glow in the dark powder that lasts as long as the commercial stuff, it's not as bright as I've shown in the video. But if there is anything extra you want to know about the process then feel free to message me.
Best comment ever " before you start pissing all over you lab " lol !
@starwars4297 I understand a lot of people don't like my voice, you can turn off the sound and turn on the subtitles if it helps.
To anyone saying this isn't his real voice.. I'm pretty sure it is. I know guys who have slightly deeper voices than this..
What's with the three periods at the end of all of your statements? it's as if you want to continue your statement, but i don't see a followup to them.
IMPORTANT NOTE
Iron contamination kills the fluorescence and phosphorescence of rare earth ions very, very easily. From what I've seen, cutting pieces of the rare earth metals with steel cutting tools may be the primary reason behind the dead flakes - the tiny pieces are enough to kill the phosphorescence. Try using tungsten carbide cutting tools instead. Another problem can be contaminated acids.
Hi, Brain&Force! Didn't think I'd see you here. Iron is also found in trace amounts in impure aluminum foil and in many hardware grade hydrochloric acids, which were both used for the aluminum nitrate. So those are some additional concerns.
Brain&Force : It's simple : don't cut your dysprosium and european. Just put them in your nitric acid.
Vrej Egon Spengler Pardon some people if they purchase more than the gram or two they intend to use for this synthesis. Assuming this isn't the only chemistry you'd ever do with rare earths, you're more likely to have large pieces that need cutting.
Vrej Egon Spengler I tend to avoid that now. Tungsten carbide or zirconia cutting materials work great.
Amos Zoeller You can just dip your rare earth metal into the acid for a short period. You could just put a small drop of HNO3 in a beaker or petri dish and put the metal on it.
@LolzICanFly If you check the video description you'll find all the chemicals linked in previous videos where they are all made.
@joemnice zinc sulfide needs to be specially processed in order it to glow. Unfortunately i never found a good procedure for this.
NurdRage yo encontré una. Haz reaccionar Zn+S para generar en total 10gm. Dopalo con 0.27 gramos de CuCl2. Mezcla bien los tres polvos y hazlos reaccionar prendiendolo. Solo ten cuidado por que harde generando una reacción exotermica muy alta. Lo que queda un polvo blanco que representa ZnS:Cu. iluminalo con un láser 405nm y veras el resultados. Mezcla los tres compuestos antes de hacerlos reaccionar.
Yo hice la prueba con 3.3grm de S, 7grm de Zn en polvo y 0.27 grm de CuCl2 (2%aprox). Se prende los fuegos artificiales y el polvo blanco iluminalo con láser violeta (405nm) y veras el resultado.
NurdRage el alto calor generado por la reacción exotermica y por la presencial del dopante genera una estructura cristalina dopada con los defectos para que la banda de energía de el efecto fosforescente en una sola reacción. Si haces videos de esto te encargo que me des los créditos correspondientes.

@Anonymouzor
The fatal problem with that question is that you have to first have a method of extraction. I don't know of any method that can separate the powders and can;t say what's better.
If you have one then let me know.
To get the glow constant, you need to ensure it heats evenly and that no part of it overheats. I'm not sure that you can do that with your current setup.
@hanleyhead right in the video, the source of all the chemicals can be found in the video description
Listening to this makes me think back to scream ....
@Glockffs
problem is maintaining a hydrogen-nitrogen atmosphere at 1300 Celsius. One leak or a mistake and my lab turns into a mushroom cloud.
1:56 LMAO
@vaibhav1803
What solvent?
I do like your garden (do you call them a "back yard" or something in Canada?) ... well, I like it anyway.
@TheBrainParalysis Don't make assumptions. I said you had to do the reaction outside because of the smoke. Thus why i walked away. I also said the door could be blown off. But i never said the microwave could catch fire.
Don't complain about facts that were never actually stated.
everything is cooler if it glows in the dark
@loquaciouskook
Thanks for watching!
Wouldn't it be easier to just flick the light switch???
Finally someone who actually knows what he’s doing
today my mom gave me a glow in the dark bracelet two of them lavender and yellow
... And?
@@scarsavage3519 And he just felt like writing a completely unnecessary, inconsequential comment, just like you.
Also me.
@@ivantheterrible7696 can I join
@vaibhav1803
yeah don't worry about it, the problem is far more difficult than i make it appear in this video. It requires a good understanding of solid-state chemistry, or a lot of time and money to do experiments, to solve.
2019 anyone? 😀
ToxicCrafterz yes xd
Hi from 2021
@phudson1
No results?
I think you missed the part of the video where it works.
Get tonic water point it with Black Light (UV light) and you get the same thing.
No, tonic water fluorescent, but not phosphorescent. If you stop the light, the tonic water stops glowing, but the powder keeps glowing. They are not the same thing,.
NurdRage for how much time the glow keeps? 1 hour ?
Rumano Loko The tonic water stops glowing immediately.
fluorescent = Does not produce light if none is present.
phosphorescent = True glow in the dark. (After charging with a bright or UV light.) To find info on commercial powders, I'd recommend looking at GlowInc.com. They have the brightest and longest-lasting of any company. In fact, in the video, I think he was comparing it against their best "glow powder", the Ultra V10. Anyway, check out their site. But be warned: you'll to want to buy something. ;-)
Leland Green Someone already answerd that, YAY!
Rumano Loko Yes, I know.
Perhaps I misunderstood your question. I thought you did not understand, but perhaps it was me that did not understand (your question). If so, sorry about that.
If you're interested in commercial glow powder, check out Glow Inc. They have the longest-glowing, and also have pages with info about how long each of their products glow. (The green is up to 24 hours!) I'm not affiliated-just a fan. :-)
@vaibhav1803
Technical names is Europium and dysprosium doped Strontium Aluminate
"SrAl2O4:Eu,Dy"
doping is 1% mol europium and 2% mol dysprosium
Ain't nobody got time for that
Then why u watchin it fool
ian odipo She does have time to watch it. Just not to do it herself.
+ian odipo I meant do the experiment ....besides why u commenting me I already see u at school
I think this is the best video about chemistery I've ever seen!!!
Do you work in a meth lab?
This is Fring's green.
dont care.
This was a joke just in case you don't understand... (I referred to the Breaking Bad's "Fring's Blue")
Oh i heve not seen that yet is it good.
Yeah, definitely.
@Mike211L usually problems arise if you didn't purify your chemicals enough, (you need to perform multiple recrystallizations of the strontium and aluminum nitrates). you also need to use distilled water.
Another problem is getting the microwave to ignite the solution, you might have to experiment with different shapes of containers or amounts of solution or even the position of the container in the microwave.
I tried this. Its illegal, see you in 2 to 4 years
Immortal wow everything's illegal who cares ? 3 things need to happen before jail dude gotta get caught aressted and tried anyone doing science for science's sake isnt likely to be caught and if caught quite unlikely to be arrested and no jury is going to convict a scientist hobbyist unless said hobbyist is making meth
How?
Boric acid is a flux for the reaction. it is stable at the temperatures involved and does not interfere with the phosphorescent process.
Boric acid does not cause dead spots, it reduces them.
The looks fun. I wonder if you can make glow in the dark salt.
I love how water is the ignition for most chemical reactions.
@vaibhav1803
This does not dissolve in organic solvents, it's a ceramic compound.
@MegaZombiefish interesting, have you tried these approaches?
Found you through the P4A this year. Enjoying the vids very much. Thanks for your efforts!
@vaibhav1803
Zone melting doesn't work for this substance.
@StressedYeti actually that just caused the more volatile chemicals to boil off before combustion could be initiated. The resulting mixture no longer had the right combination of chemicals and had terrible glow properties.
Where did i say it was household items?
@mikethomas2988 due to the chemical nature of compound, it cannot be chemically altered to be moisture. So you'll have to go with the traditional route of physically encasing it in a moisture proof resin or similar agent, i'm pretty sure you're doing that already. And yes, with the proper equipment and procedure you can make stuff as good as commercial grade. Although i'm not sure if the time/labor cost would make it competitive as opposed to buying it.
The mechanisms for the process are different.
In glow powder, the light knocks electrons up into high energy levels and stored by the dysprosium. afterward the europium releases the energy as light when the electrons come back down. I've oversimplified the theory so much that it's almost useless but that's the gist of it.
My god, the last few minutes of this video are so awesome. I love this stuff.
@zingzangzap Actually no, Zinc sulfide WAS used for decades, but the modern long life powders are all Strontium aluminate based as in this video.
*Strontium Aluminate Ceramic Glow Powder ............ BRAVO NurdRage !!!*
👏👏👏 *STANDING OVATION* 👏👏👏
@onefarmville Yes, these powders, as well as the commercial ones can be incorporated into glow in the dark paints that will retain their properties after drying.
@NurdRage dude are you kidding? your voice is half of what makes these videos awesome!
you could try actually checking the video description where i describe how to make every component
@yellowmetalcyborg electrons probably would energize. Although i'm not sure how long it would remain stable, the electrons might disrupt the crystal lattice and eventually damage it to the point that it doesn't glow anymore.
Where is the video?
if I didn't want to know... why tell me?
I'm not sure if this is already been suggested but if you pre powder all your components it will allow for a more even mix and that could potentially Aid in creating a pure and even substance
Zit okay if I call you "Father Science" from now on? Cuz YOU ROCK!
Hats off to your hard work!
its a different chemical structure than ammonium carbonate and more stable at higher temperatures, thus you cannot use ammonia reacted with carbon dioxide you made yourself, it must be urea.
@azkeyz Show me a video of the correct method of heating that controls it better and the resulting powder it produces and i'll go with it.
@DarknessGirl223 the whole point of separating them was to show which ones work under what conditions. Kinda hard to show that on video if they're all mixed up.
this is really cool! i wasnt dissappointed about the results, for making something even glow a little gives me a great sense of accomplishment
It is. The pitch is the correct, tempo is correct, noise is normal, it's raw as normal.
This is truly amazing! I thank you for taking the time to show us mortals this!
So wondering if you've gotten around to finding a better method of doing this experiment to make less dead flakes?
this is very informative, i'd been thinking about getting stuff to make glow powder and now i know that most of it is toxic. i'm sure with the right amount of materials, as well as mold making equipment, a glow in the dark rock or two could be made.
Great work, cant wait to see your progress with the morphology to glow relationship.
I didn't understand a word but they sounded cool and the glowing was awesome!
Wow, I think that was your best video yet. Very, very interesting.
Commercially pure urea is often made from the decomposition of methane, sometimes propane.
In the future you can get lab grade urea from evaporating diesel exhaust fluid (DEF), that you can purchase at most automotive supply stores, and some hardware stores. It also forms a nice crystal.
i never am goign to do any of these experiments, but i do enjoy watching them
how to spell the light used in this experiment. i tryed to listen that word but it's difficalt to listen correctly
how to make urea using chemistry. i don't want want to know how to extract urea, NH3 from urine(pee)
@blidderbla
there is no difference in physical size.
The difference in morphology corresponse to the ability to retain phosphorescence is due to the oxidation state of the crystals which has been produced. A uniform heating at a controlled environment will allow this. At any rate, the reason why there is a need for UV before observation is necessary for the electrons of the flourescent compounds to achieve a higher energy level before it is being emitted resulting from instability of the electrons staying at higher energy orbitals.
@tjiddles25
It's certainly a good idea to use higher quality equipment, but i took this problem as a challenge to do it with only household or easy to get stuff. The lab microwave is a little beyond what most people can get.
but i'm definitely investigating this further and seeing what i can come up with.
wow just how many times did u do this experiment
wow number 2 nurdrage does his first attempt in making a funny chemistry-related video. Great job!
The link you mentioned - Too much heat... Once it passes a threshold, or for too long, causes the material to degrade and no longer glow. Its a link between thermal energy and mass vs luminescence.
@simontimon2
whether you're right or wrong isn't the issue, what's creepy is that you would actually make the attempt to ascertain where i live...
hey, is this the powder I use making glow in the dark glow pipes?? I am curious because I want to find a way to make a powder with a pink or purple glao. can you help me out?
I don't know about the others but I love this voice
"Phosphorescent nail polish" is, and it looks really cool.
@Anonymouzor
yeah that would work, but the problem is like trying to separate grains of sand. It can be done, but i'll be here forever :)
those can be made at home, check the previous videos
it was inspired from over 200 messages i've received on the subject over the time i've been on youtube.
Good evening, how can I apply this powder? I can put in automotive paint and pass in iron or have to mix in something else
I'm from Brazil and found interesting
I dont understand how all these precise measurements of how much to put have been made out. i mean what the hell do you measure until you get a reaction? or how ?
+Shin Drad (MorbidPuke) You need a very precise digital scale, or better yet, liquid solutions at a given molarity so you can mix in precise ratios.
Myanameis Beestingz i see,thanks
Shin Drad Take general chemistry in high school/college and you'll get a start, or go to Khan academy and sign up for a free account and do the chemistry section.
Myanameis Beestingz i find chemistry interesting but not interesting enough to go to a college that does chemistry, i actualy dropped off after 2 years of brain seisures and 7 full paper writing every fucking day, guess im not made to learn alot
Shin Drad I understand. I have a high IQ, but I'm almost allergic to college classwork.
The commercial chemical is europium strontium aluminate, and others of other colors. You have boron substituting for the aluminum. That might make a difference.
very professional video, good job and hope u succeed in recreating a glow as strong and consistent as the commercial glow!!
great work! of course, do a study about it! i think that would be the first one ever! and the uses for such a powder are endless
What causes the dead flakes and how can the be removed?? Good vid as usual!! Thanks!!
I think your chemistry is good. Just refine the heating process. Have you tried a different way to heat it?
"before you get any stupid ideas and start peeing everywhere."
This person knows that we know where to get certain chemicals and not only respects that fact or the fact that we nerds will look for where to get them if we don't know, for that alone, I subscribed.
Thank you for an inside look into your lab.
Specifically say you CANNOT use natual urea because it has impurities, proteins, toxins, metals and other things naturally excreted. You have to use artificial urea because it's pure and does not contain the interferences that disrupt phosphorescence.
HI! I was wondering about the lightfastness of the glow... will it still continue to glow forever? does pure Europium glow on its own? great vid, thanks.
All of this is caused because of coordination complexes. I'd recommend you a book called "Chemistry the central science" by Theodore Brown.
Great tutorial .. Too bad I only have 1 microwave ... Would it work in an oven ?
fertilizer companies generally use ammonia and carbondioxide for producing urea. to produce ammonia, they distilate air to provide the nitrogen and hydrogen, and use a nickel catalyst to get the reaction started (ofc, they do that in a reactor with high temperature and high pressure levels.)
Where did you buy the plastic containers? I live in Germany and I can't find them here.
@janka19931993 yeah, just remember not to stand in front of the microwave in case it explodes. I'm not joking, at higher amounts, this stuff could explode.
Fascinating experiment! Have you conducted any more since then? Btw, what is the best online source for the brightest/longest lasting strontium aluminate (Eu, Dy doped of course).
@tvanymesic
Try separating grains of sand, that's what you're asking me to do.
ahh that professional nuclear area 51 anarchy voice LOL. Awesome teacher LOL and great detail
