摘要： 通过简单的没有任何模板辅助下的水热方法合成了分散性良好，尺寸均一的桑葚状CaF2纳米材料。综合采用X射线粉末衍射(XRD)、场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)对产物的结构、形貌、尺寸进行表征，发现CaF2纳米材料由尺寸约为50 nm的纳米粒子构成。通过对不同反应阶段产物的分析，提出了其形成机理。此外，还进一步研究了Yb3+掺杂的CaF2近红外发光性质。

Abstract: Highly uniform and well-dispersed mulberry-like nanostructures of CaF2 were synthesized by a hydrothermal method without the assistance of any templates or surfactants. The 3D hierarchical CaF2 mulberry-like nanostructures with size about 450nm are assembled by numerous nanocrystals. X-Ray diffraction, scanning electron microscopy and transmission electron microscopy were used to characterize the samples. The formation process of the nanostructures was investigated by time dependent experiments. In addition, the luminescence of Yb3+-doped CaF2 nanostructures were discussed and of particular interest for various photonic applications in ionic crystals and glasses.

Key words: CaF2∶Yb3+, Nanomaterial; Luminescence property
