Abstract
A series of barium-tungstate-based phosphors doped with different concentrations of Dy 3+ were synthesized by solid-state reaction method. Photoluminescence properties and decay lifetime of Dy 3+ -doped BaWO 4 samples were studied. The results indicated that luminescent properties of BaWO 4 :Dy 3+ depended on the Dy 3+ concentration, and the inner energy could transfer from to Dy 3+ . The quality of the light was checked by estimating CIE parameters, and the results showed that BaWO 4 :Dy 3+ was a potential candidate as blue-green luminescent materials in white LED because of its excellent emission spectrum excited by UV light.
