THE 2-MINUTE RULE FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt shows a short decay time ingredient (∼100 ns), but will also a protracted (ms) decay time is noticed. The brief decay time is ascribed to some defect-associated emission of ZnS, and isn't through the decay in the changeover of the Mn2+ impurity. The transition with the Mn2+ features a
