THE BASIC PRINCIPLES OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed exhibits a brief decay time element (∼100 ns), and also a long (ms) decay time is noticed. The quick decay time is ascribed to your defect-associated emission of ZnS, and isn't in the decay of the changeover from the Mn2+ impurity. The transition from the Mn2+ includes a `standard�?decay of
