THE 5-SECOND TRICK FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt displays a brief decay time part (∼100 ns), but also a long (ms) decay time is noticed. The short decay time is ascribed to some defect-linked emission of ZnS, and isn't from the decay on the changeover on the Mn2+ impurity. The transition of the Mn2+ provides a `standard�?decay of
