A REVIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact exhibits a brief decay time component (∼one hundred ns), but will also a protracted (ms) decay time is observed. The shorter decay time is ascribed to the defect-linked emission of ZnS, and isn't through the decay of the transition with the Mn2+ impurity. The transition on the Mn2+ has a `typ
