NOT KNOWN DETAILS ABOUT CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed shows a brief decay time element (∼a hundred ns), but additionally a protracted (ms) decay time is noticed. The brief decay time is ascribed into a defect-linked emission of ZnS, and is not from the decay of your transition of your Mn2+ impurity. The changeover in the Mn2+ provides a `normalï¿
