Abstract
Polycrystalline ZnS:Cu:Mn:Dy (Cl) phosphors with varying concentration of Cu and fixed concentrations of Mn and Dy have been prepared, XRD studies showed that the cubic — hexagonal phase transformation in the phosphors is a sensitive function of Cu concentration so that cubic phase dominates at higher Cu concentrations. It has also been found that Cu enters into the cubic ZnS phase as Cu+ while in hexagonal ZnS phase as Cu2+ and their solubility limits are around 0.1 wt.% and 0.25 wt.% respectively. Attempt has been made to confirm the existence of Cu+ in cubic phase and Cu2+ in hexagonal phase from EL emission spectra of the phosphors.
