Effect of temperature on the crystallite size of Lanthanum Cerium Oxide (La2Ce2O7) and its optical properties

Abstract

The effect of the calcination process on the crystallite size and optical properties of Lanthanum Cerium Oxide (La2Ce2O7) nanopowders synthesized using co-precipitation process were reported. X-ray diffraction analysis revealed that the synthesized nanopowders calcined at various temperatures have cubic fluorite phase. Thermal Gravimetric Analysis (TGA), X-ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS), Transmission Electron Microscopy (TEM), Laser Raman Spectroscopy, and UVvisible spectroscopy were utilized to characterize phase structure and morphology of the products.
