NOT KNOWN FACTS ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed exhibits a short decay time ingredient (∼one hundred ns), but additionally a long (ms) decay time is noticed. The quick decay time is ascribed to the defect-linked emission of ZnS, and is not within the decay from the changeover of your Mn2+ impurity. The transition on the Mn2+ provides a `typ
