THE BEST SIDE OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed reveals a short decay time component (∼a hundred ns), but in addition a lengthy (ms) decay time is noticed. The short decay time is ascribed to some defect-similar emission of ZnS, and is not in the decay from the transition in the Mn2+ impurity. The changeover of your Mn2+ contains a `regular
