THE BASIC PRINCIPLES OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed reveals a brief decay time component (∼one hundred ns), but also a protracted (ms) decay time is observed. The shorter decay time is ascribed to a defect-similar emission of ZnS, and is not within the decay in the changeover of your Mn2+ impurity. The transition from the Mn2+ contains a `typic
