  • 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

    Europium and dysprosium nitrates: • Make Europium and Dysp...
    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.

    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!

    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.

    • @amosz5726
      @amosz5726 10 років тому +1

      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.

    • @vmelkon
      @vmelkon 10 років тому

      Brain&Force : It's simple : don't cut your dysprosium and european. Just put them in your nitric acid.

    • @amosz5726
      @amosz5726 10 років тому +2

      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.

    • @brainandforce
      @brainandforce 10 років тому

      Vrej Egon Spengler I tend to avoid that now. Tungsten carbide or zirconia cutting materials work great.

    • @vmelkon
      @vmelkon 10 років тому

      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.

      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.

    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.

  • @Lessinath

      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,.

      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. ;-)

      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. :-)

    @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.

  • @NurdRage
    @NurdRage  14 років тому

    @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.

  • @NurdRage
    @NurdRage  15 років тому

    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.

    @hochunloong 14 років тому

    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.

      +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.

      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

    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.

    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.)

    @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).
