“…Altogether the above mentioned observations designates an improved cross-linking (CL) in the glass systems with rising content of Pb 2+ . 62 The two-photon-absorption coefficient (2PAC) can be assessed with aid of optical band gap and lesser 2PAC value marks the BTSZPX glasses to be beneficial for non-linear optical devices.…”

Several radiation shielding parameters for (75-x)B2O3-10TeO2-13SrCO3 -2ZnO-xPbO glasses were evaluated between 0.284 and 1.333 MeV. The PbO content in the glass has a positive relationship with the density of the glasses, leading to BTSZP0, the glass with no PbO, having the smallest density, while BTSZP5, which has 40 PbO mol%, has the greatest density. Radiation shielding parameters such as mass attenuation coefficients and other related factors were computed, and relationships between PbO content, energy, and density are graphed. Linear attenuation coefficient (LAC) is reported and we evaluated the impact of density on the LAC values. By adding more PbO atoms, the density of the samples increased, leading to a higher LAC. The BTSZP0 sample has the highest HVL at all tested energies, with the BTSZP5 sample having the lowest HVL. Mean free path (MFP) has an inverse relationship with the density of each sample but increases with greater incoming photon energy. The effective atomic number (Zeff) values peak at low photon energies and rise significantly with increasing PbO content. The MFP and TVL of the BTSZP glasses are compared against previously tested glass samples at a set energy, and the values demosntrated the effectiveness of the BTSZP glasses.

“…Bi 2 O 3 participates in the glassy network through two structural groups, BiO 6 and BiO 3 . Even minor additions of Bi 2 O 3 to glass formers, like borates, lead to increased density and substantial changes in their physical properties [7][8][9].…”

The exploration of optoelectronic materials with distinctive properties is still ongoing. To this end, a series of quaternary glassy materials of the composition 15Na2O–65B2O3–(20–x)Bi2O3–xCr2O3, denoted as NBBC, is synthesized using the melt quenching method, where x = 0.0, 2.0, 4.0, 6.0, 8.0, and 10.0 mol%. X-ray diffraction (XRD) confirms that the glasses under investigation are amorphous, except for the sample with a molar ratio of 10% Cr2O3, which showed a polycrystalline structure. FTIR analysis of the NBBC glasses reveals structural changes affecting Bi-O and B-O vibrations, suggesting a correlation between composition and optical properties. Interestingly, the bandgap energy of the NBBC glasses, determined optically, demonstrates a reduction from 2.881 eV to 1.941 eV with increasing Cr2O3 content. Conversely, the tail energy exhibits an opposite trend. The observed reduction in the bandgap with increasing Cr-ions is attributed to the introduction of chromium in the glassy matrix which changes the electronic structure and enhances the light absorption efficiency. Furthermore, various optical parameters are calculated, such as the optical constants, dielectric constants, loss energy, the density of coverage, sheet resistance, the figure of merit factor, and dispersion parameters. Notably, all of these parameters demonstrate a remarkable sensitivity to the gradual increment of chromium ions. These findings imply that the NBBC glasses could be appropriate for optoelectronic purposes.

“…These materials are used to protect the human and environment from the hazard of the ionizing radiation. Lead and concrete are the two most popular materials used as radiation shields [4,5]. In addition, glasses in the current days are widely in the radiation shielding applications for many reasons.…”

In this work, we studied the radiation shielding properties of aluminosilicate glasses with constant SiO2 content. By applying Phy-X software, we calculated different radiation attenuation factors for the chosen glasses. The linear attenuation coefficient (LAC) for the chosen CaO–Al2O3–SiO2 glass systems showed an exponential decrease as the energy changes from 0.015 to 15 MeV. For the glass with composition of 35CaO-5Al2O3-60SiO2, the LAC decreases from 29.80 to 1.279 cm-1 between 0.015 and 0.05 MeV. The LAC decreases with the increase in the Al2O3 content. The minimum LAC is found for the glass with the composition of 20CaO-20Al2O3-60SiO2. The effective atomic number (Zeff) was reported, and we found that the highest Zeff is occurred at 0.015 MeV and varied between 14.55 and 16.09. The Zeff decreases when we replaced the CaO by Al2O3. The half value layer was reported and we discussed the impact of the density of the glasses on the HVL values. In the low energy range, the HVL values are small and the different compositions have close HVL. For E>0.08 MeV, the HVL is higher than 1 cm for all glasses, while for E> 0.2 MeV, the HVL becomes higher than 2 cm for all glasses. The glass with composition of 35CaO-5Al2O3-60SiO2 has better attenuation performance than the other glasses in this study.
