FASCINATION ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact displays a short decay time ingredient (∼a hundred ns), but will also a lengthy (ms) decay time is noticed. The shorter decay time is ascribed into a defect-related emission of ZnS, and is not within the decay in the transition in the Mn2+ impurity. The changeover of the Mn2+ features a `usua
