A SECRET WEAPON FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact exhibits a short decay time component (∼100 ns), but in addition a long (ms) decay time is observed. The limited decay time is ascribed to some defect-related emission of ZnS, and isn't in the decay of your transition of your Mn2+ impurity. The transition in the Mn2+ provides a `regular�?de
