What makes LEDs particularly special is that the size of the depletion zone determines the wavelength-and thus the color-of the light produced. By carefully tuning the materials used, we can create LEDs that emit anything from deep reds to vibrant blues and everything in between. For white light, we take this process a step further. A blue LED is coated with a phosphor material that absorbs some of the blue light and re-emits it as yellow. When the remaining blue light mixes with this yellow emission, the result is a warm, white light that’s become a staple in homes and industries.
Sir what are holes...as I know it's a space of an electron is that right if it is than how can electron have it's space because the electron is not steady it's moving in an axis

It's very useful to my presentation tqq so much
Made the subject easy 🙏
Very helpful, but how do you get the different colours in a clear LED?
Thanks💖
Different types of semiconductors give different colours Ga As gives infrared Ga p gives red or green
Thanks a lot, this video motivated m to learn more about pn diodes,thx
Thank you so much. Plz share to reach more people.
It's very insightful and very glorious video for L.E.D topics.
I liked it.
Nice sir this is very helpful for my study's ...... I think LEDs is a brand name
Super sir for easy in well explain hepling ur vedioes helping lot sir

Nice knowledge and helpfull also
Superb explanation
Thanks
thanks.
Good mama keep it up
Very helpful , nice information sir👍
Why does ordinary LEd doesn't emit, is there any difference in their structure ?
Sir transistor par video banho
Why electrons fall from cb to vb
Good teaching 👍
Thank you.
Tq for this useful post
Thank you. Please Share and Support us.
Nice sir
Thank you. Plz, share to reach more people.
Sir how to find out the emitting power
❤️🌸
Thank you for your time. We'll create better and more courses very soon.
