The luminescence of nanocrystalline ZnS : Mn2+ certainly demonstrates a brief decay time element (∼100 ns), but in addition a long (ms) decay time is observed. The shorter decay time is ascribed into a defect-related emission of ZnS, and isn't in the decay of the transition with the Mn2+ impurity. The transition of your Mn2+ features a `usual�?decay of about one.9 ms. Based upon our observations, we conclude that doped semiconductor nanoparticles tend not to sort a whole new course of luminescent resources, combining a large efficiency with a short (ns) decay time.
