In this research work, we have synthesized pure and Ce1-xNdxO2 (x = 0.08 and 0.10) nanomaterials using microwave assisted co-precipitation method. The structural and optical properties have been studied using X-ray diffraction (XRD), Transmission electron microscopy (TEM) and Raman spectroscopy. The XRD and Raman spectroscopy results are in good agreement for cubic fluorite structure and phase purity with Nd-doping concentration in CeO2. From TEM results we have measured the particles size in 6.55 nm-7.39 nm range with spherical morphology. The Raman bands show red shift with increased Nd-doping on the Ce lattice site. The longitudinal, transverse and Frenkel type defects can be observed to be more pronounced with increased doping. The absorption band of UV-Vis-NIR spectra below 400 nm is showing red shift, which indicates Ce3+ oxidation state with incorporation of Nd3+ ions. The results are explained to show promotion of oxygen vacancy and defects with the increased Nd-doping; make them promising material for optoelectronics and photocatalytic applications. |
