AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in truth exhibits a short decay time part (∼100 ns), but also an extended (ms) decay time is noticed. The small decay time is ascribed to your defect-relevant emission of ZnS, and is not in the decay from the changeover with the Mn2+ impurity. The changeover of the Mn2+ incorporates a `ordinary�?de
