Luminescent materials absorb light and store its energy in chemical form. The energy is then reemitted over an interval of several minutes. The properties of luminescent paper are studied in two activities.

Do the activities Light Energy #3 Investigate material that absorbs and emits light
and Light Energy #4 What color of light charges the glowing paper?
If you had a laser pointer, you could try to "write" on the luminescent paper with it. Do you expect this to work?

How could we determine whether infrared or ultraviolet light have any effect on the luminescent paper?
