CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ indeed exhibits a short decay time element (∼one hundred ns), but additionally a long (ms) decay time is noticed. The small decay time is ascribed to your defect-relevant emission of ZnS, and is not from your decay on the transition with the Mn2+ impurity. The transition of the Mn2+ features a `norma
