A REVIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a short decay time ingredient (∼one hundred ns), but also a protracted (ms) decay time is noticed. The quick decay time is ascribed to the defect-linked emission of ZnS, and isn't within the decay on the transition with the Mn2+ impurity. The transition of your Mn2+ incorporates a `
