A Secret Weapon For CeF�?Crystal
The luminescence of nanocrystalline ZnS : Mn2+ indeed reveals a short decay time ingredient (∼one hundred ns), but also an extended (ms) decay time is observed. The shorter decay time is ascribed to the defect-relevant emission of ZnS, and is not through the decay of the transition in the Mn2+ impurity. The changeover from the Mn2+ provides a `or
