DETAILED NOTES ON CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ indeed displays a short decay time ingredient (∼a hundred ns), and also a protracted (ms) decay time is noticed. The limited decay time is ascribed into a defect-related emission of ZnS, and is not from your decay of your changeover with the Mn2+ impurity. The changeover of your Mn2+ incorporates a `
