“…Condrateet al, [29] described the structure of Bi2O3 based glasses as like that of crystalline α-Bi2O3. Although, the network of α-Bi2O3 is created by the continual linking of octahedral [BiO6] and polyhedra [BiO3] primary units by sharing corresponding vertices [23,30]. Consequently, the design of Bi2O3 primarily based glasses was developed by octahedral BiO6 units related to collective corners.…”

“…A small deviation in wavenumber with chemical composition has been seen because of an increment in the [BO 4 ] units in the glass network [35,36]. The peak at 910 cm −1 is recognized as the fundamental peak promising due to induced stretching vibrations in B−O bonds of [BO 4 ] from diborate groups [4,30]. The peak prominent at around 1190 cm −1 can be intuited to asymmetric stretching induced vibrations due to B−O bonds of [BO 4 ] units from pyro and ortho borate groups [4].…”

Investigations on Structural and Optical Properties of Various Modifier Oxides (MO = ZnO, CdO, BaO, and PbO) Containing Bismuth Borate Lithium Glasses

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.

Fabrication, physical characteristic, and gamma-photon attenuation parameters of newly developed molybdenum reinforced bismuth borate glasses

et al. 2020

To observe the direct effect of molybdenum reinforcement on nuclear radiation shielding properties, a detailed investigation was performed with a group of bismuth borate glasses. Accordingly, glass samples with the nominal compositions (65-x)B2O3 + 20Bi2O3 + 15Na2O + xMoO3: x = 0, 1.5, 3, 4.5, 6 and 7.5 wt% have been synthesized by the solid state conventional method. The samples were named as M0 (x = 0), M1 (x = 1.5), M2 (x = 3), M3 (x = 4.5), M4 (x = 6) and M5 (x = 7.5). Physical characteristics and gamma-photon attenuation properties of (M0-M5) glasses have been investigated via MCNPX simulation code and XCOM program. XRD patterns confirmed that M0-M5 glasses were in amorphous nature. The density of the prepared glasses increased from 4.4104 for M0 glass sample to 5.3012 gm cm−3, while molar volume decreased from 33.50083 to 28.92114 cm3 mol−1. The mass attenuation coefficient (μm) increased with the increment of MoO3 concentration in mol% and followed the order: (M0)μm < (M1)μm < (M2)μm < (M3)μm < (M4)μm < (M5)μm at all photon energies. The mean free path (MFP), half value layer (HVL), and tenth value layer (TVL) for the prepared glasses M0-M5 have the same trend and follow the order: (M5)MFP, HVL, TVL < (M4) MFP, HVL, TVL < (M3) MFP, HVL, TVL < (M2) MFP, HVL, TVL < (M1) MFP, HVL, TVL < (M1) MFP, HVL, TVL. The M5 glass sample (with maximum MoO3) achieved highest effective atomic number (Zeff)and equivalent atomic numbers (Zeq) values for all photon energy ranges (low-medium-high). Among all the glass samples, the exposure build-up factor (EBF) and energy absorption build-up factor (EABF) values for M5 glass sample with the highest MoO3 additive are minimum due to the low amount of photons accumulated. These results indicate that M5 glass sample theoretically provides maximum protection for gamma-rays among all the samples.
