THE BEST SIDE OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed shows a short decay time ingredient (∼a hundred ns), and also an extended (ms) decay time is noticed. The limited decay time is ascribed into a defect-relevant emission of ZnS, and isn't from the decay in the transition of your Mn2+ impurity. The transition with the Mn2+ features a `standardï¿
