摘要：

氟化铈(CeF3)具有很高的离子电导率［1］和独特的光学特性［2］, 可用于制作化学传感器和光学元器件. CeF3还是良好的固体润滑剂［3］. 近年来的研究结果表明, 与氟化物粗晶材料相比, 纳米尺度的氟化物的性能有显著的提高， 因此, 其制备方法也很受关注. 目前, 制备氟化物纳米颗粒的方法有蒸发法［4］、 微乳液法［2, 5~8］、 水醇混合溶液法［3,9］和微波固相氧化还原合成法［10］等. 但是, 水溶液直接沉淀法作为一种操作简单, 成本低, 适合批量生产的制备方法尚未见用于制备纳米CeF3颗粒.

Abstract:

Abstract A simple and effective method for preparing cerium(Ⅲ) fluoride nanoparticles was reported, which is suitable for scale production. Cerium (Ⅲ) fluoride nanoparticles were synthesized by direct precipitation from aqueous solution, without any organic solvent or surfactant involved in the whole process.  X-ray powder diffraction analysis showed that the product was a single phase. The grain sizes calculated with Scherrer equation were between 10~17 nm. The images of transmission electron microscopy confirmed that the sizes of the cerium(Ⅲ) fluoride particles were below 20 nm in diameter. Neither organic solvent nor surfactant was involved in the whole process and the particle size distribution was narrow.
