AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact exhibits a brief decay time part (∼one hundred ns), but will also a protracted (ms) decay time is observed. The quick decay time is ascribed to a defect-similar emission of ZnS, and is not from the decay of your changeover on the Mn2+ impurity. The transition with the Mn2+ has a `normal�?de
