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?
