CEF�?CRYSTAL FUNDAMENTALS EXPLAINED

The luminescence of nanocrystalline ZnS : Mn2+ in fact displays a short decay time ingredient (∼one hundred ns), and also a long (ms) decay time is noticed. The shorter decay time is ascribed into a defect-related emission of ZnS, and is not within the decay in the changeover on the Mn2+ impurity. The changeover on the Mn2+ contains a `regular�
