以普通无机盐为原料，成功合成了W6+掺杂的CeO2纳米材料。利用X 射线衍射和扫描电子显微镜等测试手段对产物的物相和形貌进行了表征。结果表明：当W6+掺入CeO2的摩尔分数小于等于30%时，所得产物均为具有单一立方萤石结构的纳米粒子。光学性质研究发现，与未掺杂的CeO2纳米材料相比，Ce0.7W0.3O2.3纳米材料表现出了不同的光吸收性能，其发光光谱上出现的蓝光发射表明，Ce0.7W0.3O2.3纳米材料在发光材料领域具有潜在的应用前景。

With ordinary inorganic salts as raw materials, CeO2 nanomaterials doped with W6+ were successfully synthesized. The phases and morphologies of as-obtained products were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively. Results show that as-obtained products are nanoparticles with single cubic fluorite structure when the mole fraction of W6+in CeO2 is equal to or less than 30%. Optical properties indicate that Ce0.7W0.3O2.3 nanomaterials exhibit different light absorption properties compared with the un-doped CeO2 nanomaterials. Blue light emission appeared on the luminescent spectrum indicates that Ce0.7W0.3O2.3 nanomaterials have potential applications in the field of luminescent materials.
