The luminescence of nanocrystalline ZnS : Mn2+ in truth demonstrates a brief decay time part (∼100 ns), but additionally a protracted (ms) decay time is noticed. The shorter decay time is ascribed to your defect-associated emission of ZnS, and is not from your decay with the changeover in the Mn2+ impurity. The transition with the Mn2+ has a `reg
