NOT KNOWN FACTUAL STATEMENTS ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed shows a brief decay time element (∼100 ns), but will also an extended (ms) decay time is noticed. The limited decay time is ascribed to the defect-relevant emission of ZnS, and isn't in the decay of the transition in the Mn2+ impurity. The changeover of the Mn2+ has a `standard�?decay of abo
