NOT KNOWN FACTUAL STATEMENTS ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in truth exhibits a short decay time part (∼a hundred ns), but additionally a protracted (ms) decay time is observed. The small decay time is ascribed to the defect-related emission of ZnS, and is not with the decay of your changeover in the Mn2+ impurity. The changeover of the Mn2+ has a `normal�?
