DETAILED NOTES ON CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt shows a brief decay time ingredient (∼one hundred ns), and also an extended (ms) decay time is observed. The limited decay time is ascribed to some defect-related emission of ZnS, and isn't from your decay with the transition in the Mn2+ impurity. The changeover of the Mn2+ features a
