The luminescence of nanocrystalline ZnS : Mn2+ indeed exhibits a short decay time element (∼100 ns), but will also an extended (ms) decay time is observed. The short decay time is ascribed to some defect-linked emission of ZnS, and isn't within the decay of your transition from the Mn2+ impurity. The transition in the Mn2+ features a `regular�?
