AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt exhibits a brief decay time element (∼100 ns), but will also a lengthy (ms) decay time is observed. The shorter decay time is ascribed into a defect-related emission of ZnS, and isn't with the decay on the transition with the Mn2+ impurity. The transition in the Mn2+ includes a `usual
