“…Finally, it can be seen from figure 12 that the maximum phonon energy [68][69][70][71] of all the examined glasses are nearly the same, which are in the range of 736-740 cm −1 . These values are slightly lower than most of tellurite glasses [63,72] but significantly lower than silicate glasses [73,74], borate glasses [75], phospahate glasses [76].…”

New tellurite glasses with composition (in mol%): 60TeO2–(30-x)ZnO–5Bi2O3–5TiO2-xB2O3 (where x = 0, 2.5, 5.0, 7.5 and 10.0) were fabricated using conventional melt quenching method. Compositional dependence of the glasses on their density, thermal, refractive index and optical properties were investigated. X-Ray Diffraction analysis was carried out to confirm the nature of the thus formed glasses. Density, refractive index, and absorption spectra were measured at room temperature from which other glass characteristics such as polaron radius, oxygen packing density, field strength, B3+ interatomic distance, band gap energy, and Urbach tail were determined. Thermal characterisation to determine the change in glass transition temperature, glass crystallisation, melting point, and glass stability was carried out using Differential Scanning Calorimetry. A discussion was made in order to understand the results in terms of the ratio of bridging oxygen to non-bridging oxygen ions (BO/NBO). It was found that the addition of B2O3 results in increasing oxygen packing density, glass transition temperature, BO/NBO ratio and band gap energy, while decreasing density, refractive index, field strength, glass stability and Urbach tail energy. With increasing B2O3 concentration density changed from 5.879 to 5.646 g/cm3, refractive index 1.875 to 1.741, working temperature range (ΔT = 660C) and phonon energy within the range of 736 – 740 cm-1.

“…It might be inferred that the existence of bismuth-barium oxide modifies the tellurite networking, resulting in a structural change from the TeO4 to TeO3 unit in the basic tellurite glass [17]. This is shown by a prominent peak at 1354cm -1 , which is related to the creation of "non-bridging oxygen" atoms within the network and serves as the main location for RE incorporation within the glass matrix [18].…”

A series of a new glass sample has been prepared with glass composition xDy2O3-(10-x) Bi2O3-20BaO-70TeO2 (where x=0,1,2,3,4,5, and 6 and mol %) have been produced through the traditional melt-quenching approach. The XRD (“X-Ray Diffraction”) pattern indicates that the glass system is amorphous by nature. The prepared glass system’s density has been examined with Archimedes’ principle, and the associated molar volume was estimated. Dy2O3 increases the density of the glass system, and it is observed that the molar volume is inversely related to the glass density. The absorption spectra from the wavelength range 200nm – 1100nm are applied to assess the glass’s optical properties. The direct and indirect optical band gap were computed using Tauc’s plots from the absorption spectra. The energy gap variation with the concentration of Dy2O3 has been discussed. The refractive index has also been calculated using the energy band gap values. Other physical parameters like electronic polarizability, and dielectric constant molar volume have been calculated. The structural and optical properties were examined via FTIR and RAMAN spectrometers.
