I have some of the materials you "charge" that will react to IR, radio shack 
used to sell "IR Remote Testers", a card with a patch of material on it that 
you'd hold to a light source, then shine your remote on it and it would 
flash a bright blue/green/white reacting to IR at close range.  I was 
thinking along the lines of something you could look through, like a lens in 
a pair glasses.
