采用水热法制备了 NaEu(MoO4)2- x (WO4) x 固溶体微晶；通过 X 射线衍射(XRD)、扫描电镜(SEM)和荧光分析(FA)对所制备的微晶进行了表征。 XRD 结果表明 NaEu(MoO4)2- x (WO4) x 微晶呈现典型的四方晶相白钨矿结构。 SEM 分析表明微晶呈米粒状。荧光分析显示,NaEu(MoO4)2- x (WO4) x 微晶在370~386 nm之间呈现 MO2-4配离子( M = Mo,W)的特征发射峰,发射波长随 x 的增大而减小；同时,Eu3+在592 nm (5 D0→7 F1)和614 nm(5 D0→7 F2)的特征发射峰均明显显现,强度随 x 的增大而逐渐增大。

NaEu(MoO4 ) 2 - x (WO4 ) x solid solution microcrystallines were synthesized by hydrother-mal method. The structure, morphology and photoluminescent properties of the microcrystallines were studied by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and fluo-rescence analysis (FA). XRD results show that NaEu(MoO4 ) 2 - x (WO4 ) x microcrystallines are all typical scheelite structure with tetragonal symmetry. SEM measurements reveal that the phosphors are rice-like particles. The fluorescence analysis (FA) results reveal that the characteristic emission peak of MO2 -4 (M = Mo, W) complex ion appears from 370 to 386 nm, and blue shifts with the in-creasing of x. Moreover, the characteristic emission peaks located at 592 nm and 614 nm of Eu3 + all appear obviously, and the intensity gradually increases with the increasing of x.
