摘　　要：多酸基纳米材料因独特的形貌、组成及广泛的应用价值而受到广泛的关注.但稀土氟化物作为一种荧光性能突出的材料与多酸形成纳米复合物还鲜有报道.本文使用化学沉淀法,在温和的水溶液条件下,成功合成出CeF3∶Tb3+掺杂磷钼酸纳米球.此外,对标题化合物进行了荧光性质的研究,在250 nm的激发波长下,该化合物表现出Tb3+离子和多酸阴离子的多重发射光谱.Polyoxometalate-based nanomaterials have received great attention due to their unique morphology, composition and wide application value. However, rare earth fluorides-polyoxometalates nanocomposites have been rarely reported to date. In this paper, CeF3∶Tb3+ doped phosphomolybdate nanospheres were synthesized successfully by chemical precipitation under mild aqueous conditions. In addition, the fluorescent properties of these compound have been studied.
