摘　　要：采用高温固相法合成Ba0.99MoO4:0.01Pr3+荧光粉。利用XRD、荧光光谱和色度坐标研究了不同掺杂离子对荧光粉发光性能的影响。结果表明:掺杂少量的V(钒),W(钨),Ti(钛)和Co(钴)未影响到BaMoO4的晶体结构,但掺杂少量的V和W能有效地提高荧光粉的发光强度,Ti的掺杂虽然也能提高其发光强度,但效果不明显,Co的掺杂降低了其发光强度。在所有掺杂离子中,V的掺杂对荧光粉发光强度的提高效果最为明显,V在荧光粉中的最佳摩尔分数为0.08。样品中加入V能提高荧光粉的发光纯度,当V的摩尔分数为0.08时,红光效果最好。The Bao.99MoO4：0.01Pr3＋ phosphors were prepared with high temperature solid-state metlaocl, lne as-synthesized phosphors were characterized by X-ray powder diffraction （XRD）, photoluminescenee excitation （PLE） ,photoluminescence （PL） spectra and the CIE chromaticity coordinates. The XRD results indicated that a small quantity V, W, Ti and Co do not affect the crystal structure of the phosphor. The PL spectra showed that the appropriate amount of V, W, Ti enhanced the emission intensity of the phosphors, the Co re- duced the emission intensity of the phosphors. The optimal V doped concentration is 0.08. The CIE chroma- ticity coordinates of the Ba0.99Mo1-yO4：0.01 Pr3＋ ,yV phosphors with different V concentration phosphors are simulated and still located in the red region, when V concentration is 0.08, the effect of the red color is the best.
