DETAILED NOTES ON CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact demonstrates a short decay time part (∼100 ns), but will also an extended (ms) decay time is noticed. The brief decay time is ascribed to a defect-relevant emission of ZnS, and isn't in the decay on the changeover of the Mn2+ impurity. The changeover from the Mn2+ contains a `usual�?decay o
