摘要： Phosphor compositions of the formula Zn1-3x/2MxX:Mn, wherein M is selected from the group consisting of the trivalent cations of Al, In, Ga, and mixtures thereof, and X is selected from the group consisting of S, Se, Te, and mixtures thereof are disclosed. Also disclosed are phosphor compositions of the formula, MX:Cu,L,A wherein M is selected from the divalent ions of Sr, Mg, Ca, Ba, X is selected from the group consisting of S, Se, Te, and mixtures thereof, and mixtures thereof, L is selected from the group consisting of the trivalent cations of the lanthanides, Al, In, Ga, Sc, and mixtures thereof, and A is selected from the alkali metal ions or mixtures thereof. Emission chromaticity of the phosphors is controlled by varying codopant concentrations. Electroluminescent devices comprising the phosphors also are disclosed.
