“…1) [3,4,15,16]. While the 550-670 cm − 1 region bands are attributed to the stretching modes of both Ge-O-Ge and Pb-O bonds, the IR absorption bands situated at about 520 cm − 1 are found to arise from the symmetric stretching modes of Ge-O-Ge bonds associated with three-membered [GeO 4 ] rings in the glass network [3,4].…”

“…Borate glasses doped with Na + / Li + / Ag + are called the fast ion conductors (FIC) and they are potential candidates for use in solid state batteries [6,7]. This kind of electrical conduction helps them to be used as potential candidates for solid state electrolytes in electrochemical devices, such as batteries, smart windows and chemical sensors [8].…”

A series of borate glasses with the composition x(SrO) · (50 – x)V2O5 ·0.5(B2O3) where x = 0, 0.1, 0.2, 0.3 and 0.4 were prepared by melt-quenching technique. The non-crystalline nature of the glasses has been established by XRD studies. Room temperature density and DC electrical conductivity of the samples were investigated in the temperature range of 300 K to 443 K. The molar volume and oxygen packing density (OPD) were estimated. The results show that the density, molar volume and OPD decrease with the increasing of SrO mole fraction. The DC electrical conductivity data has been analyzed in the light of Mott’s small polaron hopping (SPH) model and the activation energies were estimated. The conductivity was observed to rapidly fall and activation energy was found to increase when SrO was incorporated into the glass network. This may indicate that Sr+ ions have not contributed to the total conductivity and the observed conductivity may be of polaronic type only, which is due to the hopping of electrons between multivalent states of vanadium. Various small polaron hopping parameters such as small polaron radius, rp, effective dielectric constant, ∈p, polaron band width, J, optical phonon frequency, νo, small polaron coupling constant, γp, density of states at Fermi level, N(EF) were estimated and discussed.
