CEF�?CRYSTAL - AN OVERVIEW

The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a brief decay time element (∼100 ns), and also a long (ms) decay time is observed. The shorter decay time is ascribed to the defect-connected emission of ZnS, and is not from the decay from the transition on the Mn2+ impurity. The transition from the Mn2+ provides a `ordinary�?dec
