A REVIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly demonstrates a short decay time element (∼one hundred ns), but additionally a long (ms) decay time is noticed. The quick decay time is ascribed to your defect-related emission of ZnS, and is not in the decay of your changeover on the Mn2+ impurity. The changeover with the Mn2+ features a `n
