CEF�?CRYSTAL - AN OVERVIEW

The luminescence of nanocrystalline ZnS : Mn2+ in fact shows a short decay time component (∼a hundred ns), and also a protracted (ms) decay time is observed. The shorter decay time is ascribed to your defect-relevant emission of ZnS, and isn't from your decay of your transition with the Mn2+ impurity. The changeover in the Mn2+ has a `typical�?
