Structural and conductivity analysis on cerium fluoride nanoparticles prepared by sonication assisted method

The article deals with the effect of sonication on ionic conductivity of cerium fluoride. Cerium fluoride nanoparticles have been prepared by simple precipitation method from aqueous solution with sonication assistance. The structural and morphology of the nanoparticles prepared have been studied using X-ray Diffraction (XRD) and Field Emission Scanning Electron Microscopic (FESEM) analysis. The morphological analysis confirms the formation of nanorods. Ac impedance spectroscopy has been used to study the ion conduction and conductivity of the prepared nanoparticles. The surface area of the prepared nanoparticles has been studied by nitrogen adsorption–desorption analysis. From the impedance spectra analysis the sample prepared at 2 h sonication time is found to have high ionic conductivity. The conductance spectra show an orderly shifting which is due to the effect of sonication. The temperature dependence of conductivity follows the Arrhenius behavior.
