Influence of Vanadium Oxide on the Optical and Electrical Properties of Li (Oxide or Fluoride) Borate Glasses

Abstract Binary glass systems of the chemical composition 0.25Li 2 O–0.75B O 3 and 0.25LiF–0.75B with different additive ratios V 5 were prepared using melt-quenching method. Characterization was carried out through techniques such as Fourier-transform infrared (FTIR) ultraviolet–visible absorption (UV–visible) spectroscopy. Optical electrical properties have been investigated in order to recognize role glass. FTIR spectra studied glasses expose repetitive vibration curves limited variations. BO 4 are basic constituent units addition F case fluoro-borate glasses. Shifting a higher wavelength optical decrease band gap values via increasing content confirms formation non-bridging oxygen (NBO). The ac-electrical conductivity ( ? ac ) dielectric constants ? ?) samples frequency range 10 Hz–8 MHz. ionic conduction takes place by Li-ion movement all samples. electronic borate can be explained hopping between 4+ 5+ . results show excellent low concentration vanadium oxide.
