Jinx,
There are substances which absorb visible wavelengths and fluoresce in IR.
These are susually organic dyes. Search for IR Dyes in any search engines.
The problem however will be their stability and cost and these chemicals come
with big warning labels(about handling these chemicals). Usually these dyes
absorb around green.
Wouldn't you prefer to use a some sort of night vison google(Edmund
Scientific) and use simple IR led's to illuminate the objects. They work very
well.
