“…The outcomes of M behavior are compatible with the obtained data for E g . This behavior is similar to that reported before in [6,[46][47][48]. In fact, the obtained reduction in M values of the present glasses lies within the range 0.397 to 0.384, which are in good harmony with those of non-linear optical values; 0.35-0.45.…”

“…This behavior can be justified through E g attitude. In fact, the decrement behavior of E g of all glass samples increases the nonlinear features [45,46]. As previously stated, increasing NiO content in our glasses results in a compact glass matrix with a high NBO concentration and, as a result, a drop in E g is also obtained.…”

Optical and radiation shielding features of NiO-CdO-BaO borosilicate glasses

et al. 2022

We report on the optical and radiation shielding features of NiO-CdO-BaO borosilicate glasses in the UV-Vis-NIR range. The presence of Ni2+ cations in the octahedral site is emphasized by the absorption band at about 434-462 nm originating from 3A2g(F) → 3T1g(P) electronic transitions in the visible range. Also, this absorption band makes the present glass samples good candidates for optical filter applications within the visible range. Moreover, the most remarkable absorption band at about 966–986 nm due to Ni2+ cations in the tetrahedral site; 3T1(F) → 3A2(F) electronic transitions. The noticed increase in this absorption band reflects the increased heat-absorbing ability of the present glasses with further NiO doping. This result makes the present glass samples possible for solar thermal collectors. The reduction of the optical band gap (Eg) values from 3.16 to 2.95 eV can be explained by the creation of nonbridging oxygens produced by the existence of Ni2+ cations in the octahedral site. The electronic polarizability (α0 -2) and optical basicity (˄ th ) values showed a slight increase with a further increase in the NiO: CdO ratio. The values of metallization criterion (M) decreased from 0.397 to 0.384 with more concentrations of NiO which agrees with the obtained data for E g. The third-order nonlinear susceptibility (χ(3)) and nonlinear refractive index (n 2) values introduced an increment behavior with more concentrations of NiO. This behavior can be justified by the decreasing behavior of E g. On the other hand, our glass samples are good attenuators against the low energy radiation, since the linear attenuation coefficient is high (from 0.449 to 0.442 cm-1) at 0.284 MeV.

“…In general, FTIR analysis is a helpful non-destructive tool for evaluating compositional and structural changes of glass materials because it provides important information about the distribution of structural groups inside the glasses [37]. The effect of nickel oxide on the structural properties of the CaO-Li 2 O-SiO 2 glass system was examined by obtaining FTIR spectra in the range of 400-1400 cm À1 , as shown in Fig.…”

Glasses with the composition (11.5 − ×) CaO − 23.5Li2O − 65SiO2: × NiO mol. % (0 $$\le \times \leq$$ ≤ × ≤ 11.5) were synthesized by melt-quenching method. And a number of physical parameters have been established. The refractive index and energy gap were also used to estimate the metallization criterion, where these glasses have shown values fallings between high (insulators) and low (metals), indicating that they are semiconductors. The XRD pattern shows the amorphous nature of investigated glasses. A number of spectroscopic analyses of the studied glasses were performed, in relation to NiO content, including Fourier transform infrared (FTIR) and UV–Visible diffuse reflectance spectroscopy (DRS). Due to compositional changes, FTIR measurements have revealed structural changes in the glass network. Furthermore, with increasing NiO content, the asymmetrical bands of silicate units increase. The creation of Ni–O–Si bonds in the silicate matrix has been attributed to the introducing heavier Ni+2 as [NiO4]2− tetrahedral species in substitution of the lighter silicon ion in the [SiO4]4− network, but it could also operate as a network modifier in glass materials. The Ni2+ ion may have behaved as a network intermediary, causing more compact structure. The mechanism of charge transfer in the glass compositions under investigation is studied using broadband dielectric spectroscopy. For the first time, the relationship between the hopping time of free ions and dc conductivity is illustrated. All of the glasses under investigation have the same charge transport mechanism. The results suggest the semiconducting nature of these glasses.

“…Borosilicate glasses (BSG) are utilized in various contexts due to their properties, including strong thermal conductivity, chemical stability, and resistance to thermal shock [1]. The mixed network formers in BSG had high-interest levels in recent years because they can combine the two desirable properties of stability silicate glasses and borate glasses, which acquire higher solubility transition metal ions [2]. They are included in different applications; glassware for the home and laboratory, ion conductors with optical and radioactive waste packaging, biomedical implant systems in bone splicing, and tissue engineering are just a few examples [3].…”

Influence NiO on the structure, elastic properties and buildup factor of BaO-CdO-borosilicate glasses

et al. 2023

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).
