Size controlled synthesis of pure CeO2 and ZnO COATED CeO2 core-shell nanoparicles for opto-electronic applications

In this study we report the fabrication of pure CeCO₂, ZnO deposited CeCO₂ hybrid core-shell nanoparticles by simple and cost effective co precipitation method. The as synthesized samples were characterized by various experimental techniques such as XRD (X-ray diffraction), FTIR (Fourier Transform Infrared Spectroscopy), UV-Vis absorbance and HRTEM (High Field Transmission Tunneling Microscopy) measurements. XRD results confirm the Cubic fluorite structure for CeO₂ and hexagonal structure for ZnO nanoparticles. Functional groups present in the core-shell nanoparticles was investigated by FTIR The optical absorbance was measured by UV-vis spectrometer. The formation of core-shell nanostructure was further confirmed by HRTEM studies.
