Phase Evolution and Structural, Morphological Studies for the Influence of Ceric Oxide Doped Srtio3 Perovskite System

Abstract

            CeO₂ is a very important rare earth material for technologically, and it was doped with different weight ratio concentrations of (0, 1, and 3 %) SrTiO₃ ceramic compound was synthesized by conventional SSR method. The prepared ceramic sample has confirms structural phase formation investigated by powder X-ray diffraction patterns and it reveals that a cubic perovskite phase with space group pm3m. The functional properties of metal oxide molecular structure or metal oxide vibrations and elements present were investigated by Fourier transform infrared spectroscopy (FTIR). Raman spectrum justifies the formation of cubic perovskite phase structure and presence of local order and disorder factor in Ce doped SrTiO₃ compounds. The surface morphology of the prepared ceramic compound has polydispersed ,irregular shape based on a cuboidal morphology with aggregation and the particle having lower surface energy were estimated by FESEM analysis. The UV-Visible spectra exhibits that distinctive shifted towards higher wavelength shows strong optical behavior of pure and cerium doped SrTiO₃ ceramic sample. The elemental distribution of the chemical composites and to increase the dopant composition of pure and cerium doped SrTiO₃ ceramic sample also identified by EDX spectra analysis. XPS spectra was recorded the information about oxidation state and surface chemical composition are presents in each elements of prepared ceramic compounds.
