THE SINGLE BEST STRATEGY TO USE FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a brief decay time part (∼one hundred ns), but also a long (ms) decay time is noticed. The small decay time is ascribed to the defect-connected emission of ZnS, and isn't through the decay of the transition on the Mn2+ impurity. The changeover on the Mn2+ provides a `usual�?decay
