The luminescence of nanocrystalline ZnS : Mn2+ indeed reveals a brief decay time part (∼one hundred ns), and also a lengthy (ms) decay time is noticed. The small decay time is ascribed to the defect-relevant emission of ZnS, and isn't from the decay of the changeover of your Mn2+ impurity. The changeover with the Mn2+ provides a `standard�?decay of about 1.9 ms. Dependant on our observations, we conclude that doped semiconductor nanoparticles do not variety a different course of luminescent resources, combining a large efficiency with a short (ns) decay time.
