| Abstract |
| The present work points to highlight the physical, structural and the optical properties
of some semiconducting V2O5-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 V2O5 increases (or decreases)
the density (or molar volume) of the glassy system due to structural changes.
Distribution of Zn3V2MoO11, Zn2.5VMoO8 and Zn2V2O7 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 MoO4 polyhedra and VO4
metavanadate chains. Vibrations of MoO6 octahedra, Zn2V2O6, Zn2V2O7, Zn3V2MoO11
and VO2 are observed from the Raman spectroscopic studies. The fundamental
UV-VIS absorption spectra have been analyzed, which indicates indirect transitions.
