Got glow-in-dark paint? UV keychain flashlight? Combine the two. Imagine what you could build. Get UV LEDs from All Electronics or Electronics Goldmine. Get yellow-green "Night glo" Speedball(tm) fabric screen ink from art supply stores. (This is a very early test-video of mine from last April, shot in thumbnail mode.)

  • i was looking for the most effishant way to lite up phospher to improve lighting im hering of blue lasers being more effishent then led

  • @jayandersons Yep, violet 400nM lasers used in blu-ray work well.  They're better than blue-colored 445nM lasers from Casio projector.

  • looking for much brighter like laser on yellow phophus

  • @jayandersons Just buy a violet laser pointer on eBay. The violet ones can charge up your glow-paint. And they're WAY brighter than violet LEDs.

  • I know it is on the opposite end of the spectrum, but have you tried infrared? I am looking for something that will respond to an infrared laser.

  • @demolishunDOTcom that red orange IR phosphor does it. Expensive stuff. Radio shack sold IR detector cards with a small spot of that phosphor. You charge it up with blue light, then it glows orange when IR hits it.

  • Your drum scanner idea was how the first wire photo systems worked! AM modulating a tone with a photoresistor scanning an image and sending it down a phone line to a lamp scanning over photosensitive paper wrapped around a drum synchronized with the transmitter...

  • very cool, I love using a photo flash to power up glow in the dark stuff

  • @wbeaty

    Yeah, I would imagine. It seems upconversion materials are pretty rare. It takes more than one photon to produce a single higher energy photon. However, I wonder if one can add energy to a photon by hitting/effecting it with a charge from an electron. That is probably even more exotic. At any rate, it is fun to think about! Thanks for getting back to me.

  • crayola totally stole this idea
