چکیده انگلیسی
The novel vanadate borate glass samples with general formula 60V2O5-5P2O5-(35-x) B2O3-xGO, x = 0.5, 1, 2, 3 and 4 mol% were prepared by melt-quenching method. Graphene oxide (GO) was synthesized using the electrochemical exfoliation. The prepared samples were analyzed by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, transmission electron microscope and thermo gravimetric-differential thermal analysis. The DC conductivity of samples was found to be in the range of 10â 2 to 10â 6 S cmâ 1. The activation energies were found to be in the range of 0.47-0.17 eV. The physical studies such as density and molar volume have been investigated. The density of these glasses increases with increasing GO content. The ionic transference number of mobile ions has been estimated by DC polarization method and the results reveal that the charge transport is predominately due to ions.
