DETAILED NOTES ON CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt shows a brief decay time part (∼a hundred ns), and also a long (ms) decay time is observed. The short decay time is ascribed into a defect-similar emission of ZnS, and is not from the decay on the transition of your Mn2+ impurity. The transition on the Mn2+ has a `standard�?decay of
