THE CEF�?CRYSTAL DIARIES

The luminescence of nanocrystalline ZnS : Mn2+ in truth exhibits a brief decay time part (∼one hundred ns), but will also a lengthy (ms) decay time is observed. The quick decay time is ascribed into a defect-associated emission of ZnS, and isn't through the decay of the changeover in the Mn2+ impurity. The changeover in the Mn2+ incorporates a `t
