THE BEST SIDE OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a short decay time ingredient (∼100 ns), but will also a lengthy (ms) decay time is observed. The small decay time is ascribed to some defect-connected emission of ZnS, and isn't with the decay in the changeover in the Mn2+ impurity. The changeover of the Mn2+ incorporates a `normal
