AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt reveals a brief decay time part (∼100 ns), but also a lengthy (ms) decay time is observed. The small decay time is ascribed to some defect-relevant emission of ZnS, and is not with the decay in the changeover of your Mn2+ impurity. The transition in the Mn2+ incorporates a `ordinaryï¿
