THE DEFINITIVE GUIDE TO CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly demonstrates a brief decay time ingredient (∼100 ns), but in addition an extended (ms) decay time is observed. The small decay time is ascribed to the defect-associated emission of ZnS, and isn't from the decay in the changeover with the Mn2+ impurity. The changeover in the Mn2+ incorporate
