CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ in fact displays a brief decay time part (∼a hundred ns), but additionally a long (ms) decay time is observed. The shorter decay time is ascribed to some defect-connected emission of ZnS, and is not from the decay on the transition on the Mn2+ impurity. The changeover on the Mn2+ incorporates a `regu
