“…The addition of ZnO content into the tellurite glass system showed consistent behavior in the evaluated parameters, however, there was an extrema for the B2 glass. Previous studies also confirmed the increasing trend in the tellurite glasses with the addition of ZnO content (up to 35 mol%) …”

In the present study, zinc-molybdenum-tellurite glasses are prepared and their thermal, thermo-mechanical, viscous, and mechanical properties for mid-IR molded glass lens applications are studied. From the thermal analysis, it is found that the glass transition temperature, onset crystallization temperature, and stability parameters slightly increase with an increase in ZnO content in both series of glasses. Thermal expansion coefficient decreases from 16.56 to 14.67 Â 10 À6 K À1 as the ZnO content increased from 10 to 30 mol%. For fixed 10 mol% of MoO 3 content, Knoop hardness slightly decreases from 3009 to 2842 MPa as ZnO content increases from 10 to 30 mol% whereas it increases for 20 mol% of MoO 3 . The results indicate that the addition of ZnO and MoO 3 contents into the tellurite glass system increases bridging oxygen contribution and in turn network compactness of tellurite matrix.

“…20 Hurby's parameter, K gl = ΔT/(T m -T x ), 21 is one of the essential thermal properties of a glass. It is estimated for the PNSBi05 glass as high as 0.74 and it is higher than that of the tellurite glass, TeO 2 -ZnO-NiO (0.39), 22 and lower than iron-phosphate glass (0.78) 19 and TZNLa (1.45). 20 Structural studies.-FTIR analysis.-FTIR spectra of the Bi 2 O 3 -modified PNSiBi glasses in the frequency region of 300-3500 cm −1 were presented in the Fig.…”

Bismuth-oxyfluoride glasses with the chemical composition of P2O5+NaF+SiO2+Bi2O3 (PNSiBi) have been prepared by melt-quenching method and studied their structural and thermal properties through Raman, Fourier transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS) and differential thermal analysis. Moreover, elemental analysis of these glasses has been performed with energy-dispersive X-ray (EDX) spectroscopy. The glass transition and crystalline temperatures of the glasses have been estimated using differential thermal analysis (DTA). The vibrational modes of these glasses have been studied through Fourier transform infrared (FTIR) and micro-Raman analysis. Elemental compositions and binding energies of the PNSiBi glasses have been explored from XPS analysis. Binding energies of PNSiBi glasses have been obtained as 100 eV for Silicon (Si2p), 132 eV for Phosphorous (P2p), 157 and 163 eV for Bismuth (Bi 4 f) and 1069.7 eV for Sodium (Na1s). The valance states and binding energies of these elements unveiled orthophosphate (PO4)2− type structure, which forms trisodium phosphate [Na3(PO4)] with sodium and fluorides of BiF3, and (PF6)−. A 1 mol% Sm2O3 doped PNSiBi05Sm01 glass unveiled robust emission among other concentrations of Bi ions proposed that PNSiBi05 glass could be an effectual host for laser and other active photonic applications.

“…With the augmentation in nucleating agent NiO content, the absorption bands intensity is increased steadily, producing a peak position red shift from 421 to 428 nm. These outcomes are by Beer-Lambert-Bouguer's Law [3,40]. Besides, this absorption band increment is the motive for the present glasses' color alteration from light color to dark brown one [3]; see figure 3.…”

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.
