NOT KNOWN FACTUAL STATEMENTS ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact demonstrates a brief decay time part (∼one hundred ns), but will also a lengthy (ms) decay time is noticed. The shorter decay time is ascribed to the defect-relevant emission of ZnS, and isn't within the decay in the transition of the Mn2+ impurity. The changeover on the Mn2+ features a `regu
