THE 5-SECOND TRICK FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact displays a brief decay time component (∼100 ns), and also a protracted (ms) decay time is observed. The short decay time is ascribed to some defect-related emission of ZnS, and is not within the decay with the transition on the Mn2+ impurity. The changeover from the Mn2+ incorporates a `ordin
