Abstract

ABSTRACT: The present work points to highlight the physical, structural and the optical properties of some semiconducting V2 O5 -MoO3 -ZnO glass-nanocomposites using density, molar volume, X-ray diffraction (XRD), field effect scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and UV-VIS absorption spectra. We have observed that addition of V2 O5 increases (or decreases) the density (or molar volume) of the glassy system due to structural changes. Distribution of Zn3 V2 MoO11, Zn2.5 VMoO8 and Zn2 V2 O7 nanoparticles has been confirmed from FESEM and XRD studies. It has been observed from FTIR spectra that the network structure depends upon isolated strongly deformed M oO4 polyhedra and VO4 metavanadate chains. Vibrations of MoO6 octahedra, Zn2 V2 O6, Zn2 V2 O7, Zn3 V2 MoO11 and VO2 are observed from the Raman spectroscopic studies. The fundamental UV-VIS absorption spectra have been analyzed, which indicates indirect transitions. GRAPHICAL ABSTRACT:
