A SECRET WEAPON FOR CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed reveals a short decay time component (∼100 ns), but also a lengthy (ms) decay time is observed. The short decay time is ascribed to a defect-similar emission of ZnS, and isn't through the decay in the changeover from the Mn2+ impurity. The transition with the Mn2+ features a `standard�?decay
