%X 本文通过简单的溶液搅拌法，分别在聚合物羧甲基纤维素钠(CMCNa)和苯乙烯–顺丁烯二酸酐共聚物钠盐(SMANa)的存在下合成了CaF<sub>2</sub>微/纳米材料。电镜测试结果表明通过控制反应条件，得到具有不同尺寸和形貌的CaF<sub>2</sub>，如直径为500 nm的表面光滑的球状、表面粗糙的微米球以及由纳米线聚合而成的长度为1.5~4 μm纳米棒束。另外，研究了分别掺杂Eu<sup>3 </sup>及Tb<sup>3 </sup>后材料的荧光性质，结果显示CaF<sub>2</sub>:Eu<sup>3 </sup>与CaF<sub>2</sub>:Tb<sup>3 </sup>分别发射出耀眼的红光和绿光。<br />
In this work, a simple solution-based route was explored to synthesize CaF<sub>2</sub> micro/nanomaterials in the presence of Sodium carboxymethyl cellulose (CMCNa) or the Sodium salt of styrene-maleic anhydride copolymer (SMANa). By controlling the reaction parameters, EM characterization results indicate that CaF<sub>2</sub> with different dimensions and morphologies were prepared, such as smooth spheres with diameter of 500 nm, rough microspheres and nanowires-aggregated nanobundles with length of 1.5~4 μm. Furthermore, the photo luminescent properties of the Eu<sup>3 </sup>and Tb<sup>3 </sup> doped CaF<sub>2</sub> were investigated, and the results showed that obtained CaF<sub>2</sub>:Eu<sup>3 </sup>and CaF<sub>2</sub>:Tb<sup>3 </sup>emit bright red light and green light, respectively.
