A SECRET WEAPON FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in truth displays a brief decay time part (∼a hundred ns), but will also a long (ms) decay time is noticed. The limited decay time is ascribed to the defect-associated emission of ZnS, and is not within the decay with the changeover of the Mn2+ impurity. The transition in the Mn2+ contains a `usualï¿
