NOT KNOWN FACTUAL STATEMENTS ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a brief decay time part (∼100 ns), and also an extended (ms) decay time is noticed. The brief decay time is ascribed to your defect-associated emission of ZnS, and isn't within the decay on the changeover of your Mn2+ impurity. The changeover of the Mn2+ incorporates a `typical�?d
