“…5,6 Thermal properties of tellurite glasses from the TeO 2 -WO 3 -La 2 O 3 and TeO 2 -WO 3 -PbO have been extensively studied by D. Sushama and P. Predeep. 7 They have found that tellurite glasses containing La 2 O 3 are thermally more stable than the tellurite glasses containing PbO. The positive inuence of lanthanum oxide addition on the thermal stability of glasses of the TeO 2 -WO 3 -PbO-La 2 O 3 system has been conrmed by earlier papers.…”

“…Such reduction in defects is strongly related to the decreasing number of the NBO, by forming more bridging oxygen (BO) network bonds. It is suggested, further addition of Er 2 O 3, its role as intermediate oxides glass modifier possibly has partly become as lattice former especially at higher concentration [10]. This has created more denser and cross-linking tightly packed glass network structure.…”

In the present work, we studied the structural and optical properties of zinc-titania tellurite glass (75-x)TeO2-20ZnO-5TiO2-xEr2O3 doped with erbium ion Er3+ (where mol % : x= 0 (host), 0.5, 1, 1.5). The reported glasses were synthesized using tradition melt quench method. The X-ray diffraction and thermal profile were utilized to study the amorphous nature of the mentioned glass. Optical absorption UV-Visible-NIR spectra were measured for optical energy gap and Er3+ absorption bands analysis. Both visible and near infrared luminescence were performed at room temperature using 980 nm laser diode excitation where the optical transition mechanism of the Er3+ in the glass is finally proposed. Broad luminescence in the present glass suggests its potential for broadband optical application.

“…Moreover, TeO2 based glasses have gained more focusing from many researchers and investigators due to their unique features such as high linear and nonlinear refractive indices and good shield for radiations [11,15,[19][20][21][22]. Therefore, glasses with TeO2 as a former have many beneficial uses in the solid-state lasers applications, memory switching instruments, and solar cells [23][24][25].…”

Effects of antimony trioxide (Sb2O3) on neutron and gamma-radiation shielding parameters of tellurite vanadio-antimonite glasses with compositions 40TeO2-(60-x)V2O5-xSb2O3: 0 ≤ xSb2O3 ≤ 10 mol% coded as (TVS0-TVS10) were investigated. The mass attenuation coefficients (MAC) were evaluated using the Monte Carlo simulation code (MCNP-5) and WinXcom program for photon energies in the range of 15 keV to 15 MeV. The SRIM program was used to compute the stopping power and projected range of the charged particles, such as proton and alpha particles, on the investigated glass samples. Based on the theoretically evaluated MAC, some shielding parameters were computed, such as linear attenuation coefficient, electric cross-section, atomic cross-section, effective atomic number, half-value thickness (HVT), and the mean free path. The EXABCal program was applied to predict the level of the photons accumulation in the investigated glass samples (buildup factors). The effective cross-section for fast neutrons was computed theoretically based on the fast neutron effective removal cross-section (ΣR ) for the constituting components. Results revealed that the maximum values of MAC exceed in the range between 28.9-31.3 cm2/g with increasing the Sb2O3 substitution ratio between 0-10 mol %, respectively. In contrast, the HVT values decrease with an increase in the increment of Sb2O3 rate. The maximum (ΣR) was obtained for glass coded TVS0 among the investigated glasses. Results concluded that the higher Sb2O3 concentration in TVS glasses leads to an increase in their capability to apply in several radiation shielding applications.
