THE CEF�?CRYSTAL DIARIES

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt reveals a brief decay time component (∼a hundred ns), but in addition a long (ms) decay time is observed. The short decay time is ascribed into a defect-associated emission of ZnS, and is not from your decay in the transition with the Mn2+ impurity. The transition with the Mn2+ includ
