Mike have to go to work but will dig up some ref and show people how they can get them, that is those in journals and for free. I also have some links on pigments.
One question
usually use small red halogen lights, UV-A I beleive
How does a Halogen Lamp that is producing mostly Red and IR light, end up producing UV-A1 "violet light", in the Ultra region and then turn it into red light.

Must be via FM

Or am I missing something here

Only about .2 % of a Halogen lamp is UV. They can appear violet to purplish but that is due to a slight absorbtion in the green band by iodine vapor
Ok, Ok, I know this isn't far, due to the lighting tech manuals I have
