A series of barium-tungstate-based phosphors doped with different concentrations of Dy³⁺ were synthesized by solid-state reaction method. Photoluminescence properties and decay lifetime of Dy³⁺-doped BaWO₄ samples were studied. The results indicated that luminescent properties of BaWO₄:Dy³⁺ depended on the Dy³⁺ concentration, and the inner energy could transfer from  to Dy³⁺. The quality of the light was checked by estimating CIE parameters, and the results showed that BaWO₄:Dy³⁺ was a potential candidate as blue-green luminescent materials in white LED because of its excellent emission spectrum excited by UV light.
