“…Such this increment in Y can be attributed to the increment in the bond's strength. The values of σ for NiCdBaSi-glasses were calculated from equation (9). As shown in figure 5, σ has an increasing behavior for NiCdBaSi-glasses with more NiO additives.…”

“…For instance, barium, a non-toxic, non-bio accumulative heavy metal, may be added to improve the glass's refractive index and luster [6]. In addition, CdO, as an HMO in glass materials, has a prominent function for various purposes, including solar and fuel cells, electrodes, sensors, K etc [5,[7][8][9]. The functional significance of CdO stems from its many desirable characteristics, including its high atomic number, density, polarizability, transparency, transmission in the Vis and IR regions, thermal stability, and low electrical resistivity, besides its optical nonlinearity and unique covalent nature [7,8].…”

“…On the other hand, incorporating transition metals (TM), with their unique features, is required to develop new colored glasses that can be used in innovative optical devices [9,10]. Moreover, TM cations, like Ni, Co, Fe, etc, have diverse valences and exhibit exceptional physical features [11].…”

In this work, the structure, elasticity parameters, and buildup factor of borosilicate glasses doped with BaO, CdO and NiO have been studied. Infrared (IR) spectroscopy was utilized to study the internal structure of the present system. IR spectra are broad, especially since the superposition between the borate and silicate occurs in the same spectral region. A deconvolution process was carried out to extract these spectra into their individual bands. The N4 values were found to barely increase from 37.9 % for 1 mol% of NiO reaching 39.5 % for 4 mol% of NiO. A such increase indicates the transformation of BO3 to BO4 units with further additions of NiO. The N4 values were used along with the dissociation energies density and packing density parameters to calculate the elastic moduli; Young, shear, bulk, and Poisson ratio. The obtained values of Young’s modulus increase with further NiO additions. This increased behavior of Young’s modulus demonstrates the augmented ability of the current glasses to withstand variations in their length under lengthwise tensile tension or compression with further NiO additions. The rest of the elasticity moduli showed increased behaviors as well. These increased behaviors support the results obtained from structural properties analyses. An increment of BO4 units with decreasing the nonbridging oxygens (NBO) in the internal structure of present glasses produces an increase in the elastic parameters of these glasses. At photons energy of 0.2 MeV, the values of energy exposure buildup factor (EBF) are low for glasses that have a high concentration of CdO (low concentration of NiO), but the value of EBF is larger for glasses that have a low concentration of CdO (high concentration of NiO).
