蓝色荧光材料ZnMoO₄：Ce⁴⁺的制备及光致发光研究

摘要: 采用高温固相法成功合成了掺杂钼酸盐的ZnMoO4：Ce4+蓝色荧光材料。通过X 射线衍射（XRD）和荧光光谱等测试手段对所制备的材料的晶体结构和发光性能进行了表征。研究结果表明：实验按照理论化学计算比成功合成了ZnMoO4：Ce4+的蓝色荧光粉，该荧光粉为纯相的三斜结构；ZnMoO4：Ce4+在395 nm 处有强电子吸收，且在440 nm 处可发射高强度蓝光，其色坐标为（0.14，0.09）；此外，当Ce 含量为3 mol%时，荧光粉发光强度最佳。

Abstract: ZnMoO4:Ce4+ blue phosphors were synthesized by high temperature solid-state method. The phase formation and luminescence properties of ZnMoO4:Ce4+ were analyzed by XRD, PL and CIE. The results show that ZnMoO4:Ce4+ blue phosphors have been successfully prepared by high temperature solid state method according to theoretic ratio, and the synthesized ZnMoO4:Ce4+ has a triclinic structure with pure phase. The phosphors have strong electron absorbability of 395 nm and can emit blue light with high intensity. The CIE of ZnMoO4:Ce4+ blue phosphor is (0.14,0.09). In addition, when the concentration of Ce is 3 mol%, the luminescent intensity of ZnMoO4:Ce4+ is highest.
