CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt displays a short decay time ingredient (∼100 ns), but also a lengthy (ms) decay time is noticed. The small decay time is ascribed to some defect-similar emission of ZnS, and is not with the decay of your transition with the Mn2+ impurity. The changeover of the Mn2+ provides a `typical
