AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ in fact reveals a brief decay time ingredient (∼one hundred ns), but will also a protracted (ms) decay time is noticed. The small decay time is ascribed to the defect-related emission of ZnS, and is not from the decay on the changeover with the Mn2+ impurity. The transition from the Mn2+ features a `
