CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ in truth demonstrates a brief decay time part (∼one hundred ns), but additionally a protracted (ms) decay time is observed. The brief decay time is ascribed into a defect-related emission of ZnS, and isn't with the decay with the changeover in the Mn2+ impurity. The transition with the Mn2+ features
