DETAILED NOTES ON CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt displays a short decay time element (∼a hundred ns), but in addition a lengthy (ms) decay time is observed. The shorter decay time is ascribed into a defect-associated emission of ZnS, and isn't from your decay of your transition from the Mn2+ impurity. The changeover from the Mn2+ co
