THE CEF�?CRYSTAL DIARIES

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt shows a short decay time component (∼100 ns), but in addition a long (ms) decay time is observed. The short decay time is ascribed to a defect-associated emission of ZnS, and isn't from the decay of the changeover of your Mn2+ impurity. The changeover of your Mn2+ contains a `typicalï
