The luminescence of nanocrystalline ZnS : Mn2+ certainly reveals a short decay time ingredient (∼one hundred ns), but in addition an extended (ms) decay time is observed. The shorter decay time is ascribed to your defect-relevant emission of ZnS, and is not within the decay in the transition from the Mn2+ impurity. The transition in the Mn2+ has a `ordinary�?decay of about 1.nine ms. Depending on our observations, we conclude that doped semiconductor nanoparticles don't form a whole new class of luminescent elements, combining a high performance with a short (ns) decay time.
