Abstract

A series of barium tungstate (BaWO4) phosphors were synthesized by the solid state reaction method, and the systematic effect of Dy3+/Sr2+ doping concentration on the structural and photoluminescence (PL) properties were investigated. X-ray diffraction studies confirm the structure of the phosphors as tetragonal with space group I41/a. The PL emission spectra show two peaks in the blue and yellow regions which were tuned to produce near-white emission. The quality of the white light was checked by estimating CIE parameters. This indicates the suitability of barium–tungstate-based phosphors for near-white LED applications.
