|title: LED Flourescence|
aka: exciting phosphorescence
Different LED lights can be used to draw, or try to draw, on a sheet of phosphorescent material. If the photon energy is high enough (above green) the phosphorescent/flourescent screen will glow green. The very bright green laser will not activate the phosphorescence.
What is it about blue light that produces the glow?
What would a black light do?
