HELPING THE OTHERS REALIZE THE ADVANTAGES OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in truth demonstrates a short decay time component (∼one hundred ns), but in addition a lengthy (ms) decay time is observed. The shorter decay time is ascribed into a defect-related emission of ZnS, and is not within the decay of the transition in the Mn2+ impurity. The changeover of the Mn2+ contain
