Abstract

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.
