The luminescence of nanocrystalline ZnS : Mn2+ indeed exhibits a short decay time element (∼one hundred ns), but also a protracted (ms) decay time is observed. The small decay time is ascribed to a defect-connected emission of ZnS, and is not within the decay of the changeover from the Mn2+ impurity. The changeover in the Mn2+ incorporates a `usu
