摘要：
Cerium oxide (Ceria) nanoparticles were successfully synthesized by hydrolysis assisted co-precipitation method. As-synthesized samples are annealed at 500 degrees C and 800 degrees C respectively. Crystalline nature of the sample is analyzed by X-ray diffraction (XRD). The morphology of all the samples is investigated by transmission electron microscope (TEM) and scanning electron microscope (SEM). The average size of the nanoparticles varies between the 8 and 20 nm. Poly crystalline natures of the nanoparticles proved by selected are electron diffraction pattern (SAED). The grain size dependent absorption is demonstrated with UV-vis spectra.
