摘要：
White-light-emitting phosphors based on phosphate host matrix, KSrPO4 doped with Dy3+, were prepared by solid state reaction and their VUV luminescent properties were firstly investigated. The excitation band peaking at 125-153 nm corresponding to the absorption of PO(4)(3- )group exhibits very strong absorption. The phosphors emit warm-white luminescence under vacuum ultraviolet excitation of 147 nm, which consists of three main emission peaks located at 475, 570 and 662 nm, respectively. According to the luminescence and color chromaticity of the optimal sample KSrPO4:1 mol%Dy3+, 1.3 mol%Li+, it can be a potential candidate for mercury-free fluorescent lamps.
