CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt exhibits a brief decay time component (∼one hundred ns), but also a protracted (ms) decay time is noticed. The limited decay time is ascribed into a defect-similar emission of ZnS, and is not with the decay from the changeover of the Mn2+ impurity. The transition on the Mn2+ contains
