A REVIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a short decay time ingredient (∼one hundred ns), but in addition a lengthy (ms) decay time is noticed. The short decay time is ascribed to your defect-relevant emission of ZnS, and is not with the decay on the transition of your Mn2+ impurity. The changeover of your Mn2+ includes a
