Not sure how useful this information is but i stumbled on this effect of old hot glue on my current project.
It has a sort of Phosphorescence effect its very fast and unlike any thing i have played with in the past it looks to me to be glowing at the same frequency bit like a crime scene ,things that are Phosphorescent tend to glow at different frequencies and its a slow effect this is fast .
The hot glue absorbs ultraviolet light and re-emits that energy as visible light at that frequency where as around it its does not .
