The luminescence of nanocrystalline ZnS : Mn2+ in fact exhibits a short decay time ingredient (∼100 ns), but in addition a lengthy (ms) decay time is noticed. The brief decay time is ascribed to a defect-linked emission of ZnS, and isn't with the decay with the transition in the Mn2+ impurity. The transition of the Mn2+ provides a `ordinary�?de
