Fluorescent Zinc Sulfide Description:

With the “phosphorimeter” described in the post Glowing in the Dark, we made a series of measurements on the classic zinc sulfide phosphorus, doped with silver and also with copper. Zinc sulfide is an interesting material: ZnS is a semiconductor, ie a material with an electron-filled valence band and an empty conduction band. It is known that the energy gap between the two bands is, in pure ZnS, about 350 kJ/mol (3.6 eV). Given the large energy gap, only a very small concentration of charge carriers is present in normal temperature conditions.
