Ultraviolet LED with phosphor paint

nice!
TV without vacuum

Is this real.. ?

yeah

i need help i sound dumb but w.e what is diffrence and why would you want UV compared to regular LED?

Green LEDs won't charge up the phosphorescent paint. Neither will blue LEDs. You need violet ones.

What would happen with a laser? You said the Phos-paint "stored" the light. I would think with a laser the light would be really focused.

unless it only works with certain wavelengths of light. (hence the UV LED) but you said you could charge it with incandescent light?

Sorry if im making a stupid comment, i dont understand much about it.

Wikipediaing now.

Yep, it works well with a 405nM violet laser pulled from a dead blue-ray. The LEDs and that laser aren't really UV, that's just marketing hype. It's visible violet light. Blue and violet light can cause fluorescence. The edge of actual invisible UV starts farther out, around 380nM.

by nM you mean the actual length of the light wave?

i never put that together - that "wave lengths" of light are only visable in a particular spectrum due to their size.

i seriously learn and understand more by watching/reading youtube/wikipedia than i did in highschool

Because its INTERESTING (TO ANY TEACHER READING THIS).

CAn you make a vid of you placing it in the microwave?

with your doc.who sonic screwdriver, you make things go GREEN
