英文摘要	Scheelite-type strontium tungstate (SrWO4) phosphor powders were successfully synthesized using strontium nitrate and tungstic acid as starting materials by a gamma-ray irradiation-assisted polyacrylamide gel route. The phase purity, structure, functional groups, surface morphology, chemical composition, colorimetric, optical and photoluminescence properties of SrWO4 phosphor powders were systematically studied by various testing instruments. The crystallite size of SrWO4 phosphor powders increases with the increasing of sintering temperature. The color, optical and photoluminescence properties of SrWO4 phosphor powders are strongly dependent on the sintering temperature, carbon chain and the distortion of tetrahedral [WO4] clusters. The fluorescence emission at (310Â nm, 338Â nm, 360Â nm and 400Â nm) and 465Â nm can be ascribed to the new energy level formed by a carbon chain, amorphous SrWO4 or oxygen vacancy, and the distortion of tetrahedral [WO4] clusters, respectively. © 2020, The Minerals, Metals & Materials Society.
