THE DEFINITIVE GUIDE TO CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed displays a short decay time element (∼one hundred ns), and also a long (ms) decay time is observed. The brief decay time is ascribed to the defect-linked emission of ZnS, and is not through the decay of the transition with the Mn2+ impurity. The changeover in the Mn2+ contains a `standard�?d
