Cu~(2+)-addition effect on luminescence of ZnS:Cu,CI blue-green phosphors

摘要

ZnS:Cu,Cl blue-green phosphors were prepared by conventional solid state reaction. Copper activator of different concentrations was doped into ZnS structure at two firing steps. The luminescence characteristics dependent on Cu~(2+) doping concentration of the phosphors has been investigated for inorganic electroluminescent device.
