LITTLE KNOWN FACTS ABOUT CEF�?CRYSTAL.

The luminescence of nanocrystalline ZnS : Mn2+ certainly shows a brief decay time ingredient (∼one hundred ns), but additionally a protracted (ms) decay time is observed. The quick decay time is ascribed to a defect-similar emission of ZnS, and is not in the decay from the changeover in the Mn2+ impurity. The changeover of your Mn2+ features a `o
