The luminescence of nanocrystalline ZnS : Mn2+ in fact demonstrates a brief decay time element (∼a hundred ns), and also a long (ms) decay time is observed. The small decay time is ascribed to some defect-relevant emission of ZnS, and is not from your decay of the changeover with the Mn2+ impurity. The transition on the Mn2+ incorporates a `typic
