AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact shows a short decay time part (∼a hundred ns), but additionally a long (ms) decay time is noticed. The short decay time is ascribed to the defect-linked emission of ZnS, and isn't in the decay of the transition of your Mn2+ impurity. The transition on the Mn2+ features a `normal�?decay of a
