“…Figure 4 shows the variation of the mean free path as a function of photon energy for the PZBTS glass samples. The current PZBTS glasses are compared with recently studied materials, such as MASLN [ 61 ], PSS5 [ 62 ], Pb–Al [ 63 ], Ca/Pb-BBC1 [ 64 ] and LTM-A [ 65 ]. Among the PZBTS glasses, the lower values of mean free path are observed for 5PZBTS.…”

“…It is also convenient for thermal neutron and gamma-ray shielding. Sakar et al [ 38 ] fabricated and studied the photon and particle attenuation characteristics of CoNiFeCr–Ti/Al high entropy alloys, and their results proved that the CoNiFeCr alloy had the greatest attenuation properties of the studied alloys and could be a suitable candidate for electron, photon, alpha, and neutron shielding applications. Gul et al [ 39 ] examined the effects of B 4 C on the structure, mechanical strength, and nuclear shielding capability of NiCoFeCrW high entropy alloys.…”

“…The scientific community has recently focused on manufacturing and analyzing optical glass systems doped with heavy metal oxide (HMO) and its special applications in optics, photonic devices, and nuclear engineering [1][2][3][4][5]. Synthesis and characterization of new materials are important for several applications [6][7][8][9][10][11]. Furthermore, doping such substances with rare-earth (Re 3+ ) ions enhances their optical and electronic properties, good stability, and flexibility characteristics, allowing an intake of elements in their formulation to be accepted.…”

Herein, this study intends to reveal the impact of gamma irradiation on the structural, linear, and nonlinear optical characteristics of 47P2O5−23Na2O−6Al2O3−22PbO−0.5Er2O3−1.5Yb2O3 glass. The Er/Yb-doped lead phosphate glass samples were produced using the traditional melt quenching procedure and then treated to different doses of gamma irradiation (0, 20, 50, and 100) kGy. The amorphous phase structure of the Er/Yb-doped lead phosphate glass samples was verified through XRD patterns. Also, the shift of the FTIR peaks due to the change in bond angles, and the change in the bond length of the P–O–P bridges means the glass network stability against radiation. With increasing irradiation dosages, the energy gap dropped from 4.11 eV to 3.42 eV and then enhanced to 3.48 at 100 kGy. At the same time, the Urbach energy enhanced from 10.23 eV to 37.03 eV. The oscillator energy Eo was found between 1.55 and 1.62 eV. Also, the dispersion energy Ed varied between 2.11 eV at 100 kGy and 2.71 eV at the dose of 50 kGy. The percentage of free carrier ions to effective mass (N/m*) is in the range (4.82–8.66) × 1047 cm3/g. Besides, the lattice dielectric constant ($${\varepsilon }_{l}$$ ε l ) increased from 5.54 to 6.63 as the gamma dosages increased. Furthermore, increasing gamma doses up to 50 kGy promotes susceptibility, which subsequently declines at 100 kGy, suggesting that increasing gamma doses over 50 kGy weakens polarizability potential. While the increasing gamma doses up to 50 kGy reduces the nonlinear refractive index and then improves at 100 kGy. Overall, the nonlinear and linear research revealed that Er/Yb lead phosphate glass is being used as a promising material for gain media and optical amplifiers.
