The luminescence of nanocrystalline ZnS : Mn2+ indeed shows a short decay time part (∼100 ns), and also an extended (ms) decay time is noticed. The short decay time is ascribed to the defect-associated emission of ZnS, and isn't in the decay of your transition on the Mn2+ impurity. The changeover of your Mn2+ has a `typical�?decay of about one.
