DETAILED NOTES ON CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a short decay time element (∼100 ns), but will also an extended (ms) decay time is noticed. The brief decay time is ascribed to your defect-associated emission of ZnS, and isn't with the decay with the changeover of your Mn2+ impurity. The changeover on the Mn2+ has a `standard�?d
