Abstract :
Nanostructures of ceria co-doped with various transition metals were prepared by a simple chemical precipitation method at 400 ºC.  The structures and chemical compositions of the products were characterized by X-ray diffraction (XRD), energy dispersive spectrum (EDS) and Fourier transform infrared (FTIR) spectroscopy. The obtained products were identified to be of face-centered-cubic structure. The morphology of the doped product was analyzed by the scanning electron microscope (SEM). The room temperature PL spectra reveal that the intensity of the peak decreases due to quenching effect of doped metal ions.
