ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly exhibits a brief decay time part (∼100 ns), but also a protracted (ms) decay time is observed. The quick decay time is ascribed to your defect-connected emission of ZnS, and isn't in the decay with the changeover from the Mn2+ impurity. The transition of your Mn2+ features a `usual�?decay
