A REVIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a short decay time part (∼100 ns), but will also an extended (ms) decay time is noticed. The short decay time is ascribed into a defect-similar emission of ZnS, and is not through the decay of the transition of your Mn2+ impurity. The transition on the Mn2+ provides a `normal�?dec
