“…In fact, adding Sb 2 O 3 to the glasses leads to the enhancement of the physical properties such as the density, refractive index, thermal and mechanical durability etc. [16]. Additionally, glasses with Sb 2 O 3 exhibit novel optical properties with high transparency to infrared radiation making them potential candidate materials for non-linear optical devices.…”

“…All of the previously reported studies evaluating some systems' shielding features have been carried out either experimentally or theoretically based on XCOM software. However, there are a limited number of studies in the literature that have used the MCNP-5 code to investigate the shielding characteristics of glass samples [7][8][9][10][11][12][13][14][15][16][17][18][19]. This comprehensive study may stimulate scientists working in synchrotronbased facilities to perform experimental studies on these compounds to compare these results with their future experimental data on these samples.…”

Elastic moduli were theoretically computed using the Makishima–Mackenzie model for SiO2–Na2O–CaO glasses doped with Sb2O3 contents. The calculated elastic moduli (Young’s, bulk, shear, and longitudinal modulus) were observed to increase with an increase in the Sb2O3 contents. The microhardness showed an increase, while Poisson’s ratio decreased with the rise of the Sb2O3 contents. In addition, gamma-ray and neutron shielding parameters were evaluated for the investigated glasses. The linear attenuation coefficient (LAC) was simulated using the Monte Carlo N-particle transport code (MCNP-5). Other parameters, such as the mass attenuation coefficient (MAC), transmission factor (TF), and half-value layer, were calculated based on the simulated LAC. The addition of Sb2O3 content was observed to enhance the investigated glasses’ shielding parameters, where the highest LAC was achieved for the SCNSb10 glass with 10 mol% Sb2O3 and decreased from 0.441 to 0.154 cm−1 at gamma energies between 0.248 and 1.406 MeV. Furthermore, the fast neutron effective removal cross-section (∑R) was computed theoretically. The calculated results showed that the highest ∑R was equal to 0.0341 cm2g−1 and was obtained for the SCNSb0 glass, which had no Sb2O3 content, while the lowest ∑R was equal to 0.0286 cm2 g−1 for the SCNSb10 glass sample. The present work was carried out to examine the advantages of the soda–lime glasses with different Sb2O3 contents in several photon shielding applications, especially for radiation safety in nuclear installations.

Silica phosphate glasses strengthened with calcium oxide modifier and doped with different concentrations (0%, 0.5%, 1%, 1.5 mol%) of praseodymium (Pr3+) were synthesized by sol-gel method. The absence of sharp peaks in the x-ray diffraction (XRD) spectra confirms non-crystallinity of the glasses. Higher doping indicates increasing optical band gaps due to Burstein Moss shift, which also reflects on structural disorders at the absorption tails as validated by Urbach’s rule. The density increases with a subsequent decrease in oxygen packing density, proving the mechanical and chemical stability of the glasses. The composite glasses are multifunctional with marked absorption at 280 nm predicting its purpose as UV shielding films. Luminescence corresponding to the intra 4f transition, 〖1_D〗_2→〖1_G〗_4 in the IR region, with high transmission and low reflection losses suggests the use of the synthesized glass material for S-band telecommunications, while the radiative process involving 〖3_P〗_0→〖3_F〗_2 yields a predominant red laser source. Commission International de l’Eclairage (CIE) color coordinates observe warmer red emission corresponding to Correlated Colour Temperature (CCT) of 3200 K. The composite silica phosphate glass systems evidence the effective role of Pr3+ for photonic applications.

“…Furthermore, in all the PSAT glasses, some absorption bands originating from the 4f-4f transitions of Pr 3+ appeared at approximately 449 nm ( 3 H 4 → 3 P 2 ), 473 nm ( 3 H 4 → 3 P 1 ), 486 nm ( 3 H 4 → 3 P 0 ), 595 nm ( 3 H 4 → 1 D 2 ), 1023 nm ( 3 H 4 → 1 G 4 ), 1439 nm ( 3 H 4 → 3 F 4 ), 1540 nm ( 3 H 4 → 3 F 3 ), and 1952 nm ( 3 H 4 → 3 F 2 ). (19,25) The absorption intensity of the PSAT glasses increased with the amount of Pr 2 O 3 doping. Moreover, the absorption edges were almost the same in the PSAT glasses.…”

We fabricated Pr 3+ -activated glasses having a composition of 10SrO-5Al 2 O 3 -85TeO 2 (PSAT) for potential use as radiation detectors, and their photoluminescence (PL) and X-ray-induced scintillation properties were then characterized. The PSAT glasses showed several emission peaks in their PL spectra owing to the 4f-4f transitions of Pr 3+ . Furthermore, they exhibited typical PL decay times (0.09-0.86 ms), where the decay originated from the 4f-4f transitions of Pr 3+ . In the scintillation spectra of the PSAT glasses, three peaks at approximately 480, 618, and 636 nm were observed. The scintillation decay times were 0.747-0.840 ms, corresponding to the 4f-4f transitions of Pr 3+ . Furthermore, the PSAT glasses showed afterglow levels of 352-521 ppm, and the lowest afterglow level (352 ppm) was comparable to that of Tl-activated CsI single crystal.
