A SECRET WEAPON FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in truth displays a brief decay time part (∼one hundred ns), but in addition a long (ms) decay time is noticed. The short decay time is ascribed to the defect-associated emission of ZnS, and isn't with the decay on the transition of the Mn2+ impurity. The changeover from the Mn2+ features a `typical�
