ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in truth exhibits a brief decay time component (∼100 ns), but additionally an extended (ms) decay time is noticed. The quick decay time is ascribed to your defect-similar emission of ZnS, and isn't within the decay of the transition with the Mn2+ impurity. The transition on the Mn2+ provides a `stand
