AN UNBIASED VIEW OF CEF�?CRYSTAL

The luminescence of nanocrystalline ZnS : Mn2+ without a doubt shows a short decay time part (∼100 ns), but will also an extended (ms) decay time is noticed. The small decay time is ascribed into a defect-relevant emission of ZnS, and is not within the decay with the transition on the Mn2+ impurity. The transition in the Mn2+ contains a `usual�
