“…Metal oxides such as Bi 2 O 3 , Sb 2 O 3 , MoO 3 and Nb 2 O 5 have been added to the tellurite glass system in order to enhance the optical behavior [7,8]. Many studies on tertiary tellurite based glass have been done by various authors [9–16]. For example, Tiefeng et al .…”

A series of binary tellurite based glasses (Bi2O3)x (TeO2)100−x was prepared by melt quenching method. The density, molar volume and refractive index increase when bismuth ions Bi3+ increase, this is due to the increased polarization of the ions Bi3+ and the enhanced formation of non-bridging oxygen (NBO). The Fourier transform infrared spectroscopy (FTIR) results show the bonding of the glass sample and the optical band gap, Eopt decreases while the refractive index increases when the ion Bi3+ content increases.

“…The UE of the BiBLM glasses is smaller than that of other Bismuthate containing glasses. UE of glasses increases from BiBLM1 to BiBLM4 (i.e., 428 to 460 meV), so that it suggests the presence of less disorderliness, minimum defects, and maybe in glasses system compositional changes take place in present glasses [47][48][49][50]. From Table 5 it is noticed that both indirect and direct values follow the trend BiBLM1 > BiBLM2 > BiBLM3 > BiBLM4, also UE follows the reverse trend BiBLM4 > BiBLM3 > BiBLM2 > BiBLM1.…”

Bismuth based quaternary glasses with compositions BiBLM: 50Bi2O3–20B2O3–15Li2O–15MO (where MO = ZnO, CdO, BaO, and PbO) were processed by conventional melt quenching. The effectiveness of various modifier oxides on the optical and structural properties of the developed glasses was studied systematically by XRD, DSC, FTIR, Raman, and optical absorption (OA) measurements. The synthesized glass specimens were characterized by XRD and the patterns demonstrated an amorphous nature. The physical characteristics such as molar mass, density, and OPD values were found to increase with an increase in the molar mass of the modifier oxides, while there was a decrement in oxygen molar volume, thus resulting in decrement of complete molar volume of the prepared glasses. From DSC analysis, incorrigible reduction and enhancement of Tg and thermal stability among various modifier oxides in the glass network was noticed. Optical absorption data for glass specimens have confirmed the decrease in both direct and indirect optical band gap values among various modifier oxides incorporation. These investigations support the obtained Urbach energy (UE) and metallization criteria of synthesized glasses. The ionic characteristic for the glass specimens were confirmed by the values of electronic polarizability and electronegativity. The Raman and FT-IR spectra of the glass specimens displayed the existence of BiO3, BiO6, ZnO4, CdO4, BaO4, BO3, PbO4, and BO4 structural units within the glass matrix. These structural results can support the applications of as-developed glasses in the area of photonics.

“…This absorption is assigned to the asymmetric stretching vibrations in BO 3 and BO − 3 units [8,9,12]. The shift of this band towards higher wave number with ZnO content may be due to the formation of bridging bond Zn-O-B [13]. Another absorption band is observed at 1438 cm −1 , which is due to BO stretching of BO 3 units in varied types of borate groups [8].…”

Zinc fluoroborate glasses with compositions xZnO.(40 -x)LiF.60B 2 O3 (x = 0, 5, 10, 15, and 20) were synthesized by the melt-quench method. The amorphous nature of the glassy samples was confirmed by XRD analysis. The nature of the bonds formed and the role of various species in the composition of the glasses were examined using FTIR spectroscopy. FTIR analysis showed shifting of an absorption band with the addition of ZnO. A UV-visible study was carried out to calculate the optical band gap energy, E g . It was found that E g decreased with increase in concentration of ZnO up to x = 15 and increased slightly for x = 20 with the stepwise replacement of a nonoxide group (LiF) by an oxide group (ZnO). Urbach tail energy, E U , was found to increase from x = 0 to x = 15 and then decreased slightly for x = 20. Theoretical optical basicity, Λth , decreased with decrease in concentration of LiF.
