Abstract
Cerium oxide nanoparticles are prepared by simple precipitation method with various precipitants. The prepared samples are analyzed by XRD, FT-IR and PL. XRD confirms the occurrence of single-phase polycrystalline cubic fluorite structure with dominant orientation along (111) direction. The sharp band at 1415 cm-1 originated from –CH3 deformation and –CH2 scissoring vibrations of PVP, also A strong band at 848 and 400 cm-1 due to the envelope of the phonon band of the metal oxide (Ce-O) network obtained from FT-IR spectra. PL spectra exhibit the presence of strong blue and weak blue-green emission in the visible region. Additions of PVP strongly distress the peaks intensity of the samples.
