CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ in truth reveals a short decay time component (∼a hundred ns), but additionally a lengthy (ms) decay time is noticed. The short decay time is ascribed to your defect-associated emission of ZnS, and is not in the decay in the transition of the Mn2+ impurity. The changeover from the Mn2+ provides a `no
