WHAT DOES CEF�?CRYSTAL MEAN?

The luminescence of nanocrystalline ZnS : Mn2+ in truth displays a short decay time element (∼a hundred ns), and also a long (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 changeover of your Mn2+ impurity. The transition in the Mn2+ contains a `typical�?d
