“…Many scientists are paying more attention to the linear and nonlinear optical properties of transparent materials (glasses). These characteristics aid in the selection of appropriate glasses for specific applications [1][2][3][4][5][6][7][8][9][10][11]. Boron-based glasses are one of the most interesting glasses because of their unique physical properties, which include low cost, ease of preparation, low glass transition temperature, high refractive index, good thermal stability, and higher optical transmission in the infrared region [1,2].…”

“…In recent years, nuclear technology has been used in environmental conservation, power generation, consumer goods, medicine, scientific research, agriculture, and food processing industries [12,14,15]. Furthermore, one of the primary goals of high radiation protection efficiency (RPE) has been to find radiation shields with more appropriate properties [3][4][5][6][7][8][12][13][14][15].…”

ABSTRACT. Linear, nonlinear optical properties, photon buildup factors, and neutron shielding capability of glasses with chemical composition (65-x)B2O3-10Sb2O3-25Li2O-xBi2O3, where x = 0 (BSLB0) – 20 (BSLB20) mol% with steps of 4 mol% were examined. Molar refractivity (Rmolar) and molar polarizability (αmolar) were increased as Bi2O3 content mol% increase in the examined BSLB-glasses. The values of metallization criterion (Mcriterion) confirmed that the BSLB-glasses were non-metallic materials. The static (εstatic) and optical (εoptical) dielectric constants having the same trend of the refractive index (noptical). Values of optical electronegativity (χ*) were reduced from 0.825 for BSLB0 (Bi2O3 = 0 mol%) glasses to 0.758 for BSLB20 (Bi2O3 = 20 mol%) glasses. The linear electric/dielectric susceptibility (χ(1)) increased from 0.370 to 0.397. The nonlinear optical susceptibility (χ3) and nonlinear refractive index n2optical were enhanced by increasing Bi2O3 content in the BSLB-glasses. The BSLB20 glasses presented the least exposure and energy absorption build-up factors (EBF and EABF) at all considered thickness. BSLB20 sample achieved the best fast neutron removal cross section ( ) shield among all glasses. The total stopping powers (TSP) follows the trend (TSP)BSLB0 < (TSP)BSLB4 < (TSP)BSLB8 < (TSP)BSLB12 < (TSP)BSLB16 < (TSP)BSLB20. The electron absorbing and hence shielding capacity of the BSLB-glasses improves as their Bi2O3 content increase.

“…Also, it is reported that TeO 2 glasses have relatively high density and thus possess a good attenuation ability against gamma radiation [20][21][22]. During the preparation process of the TeO 2 -based glasses, some glasses modi ers such as ZnO and Ag 2 O are used to enhance their optical features and radiation attenuation competences [23,24]. Introducing the Er 2 O 3 ions enhances the chemical durability of glass as well as the radiation shielding features.…”

The investigation involves a comprehensive study on the mechanical and shielding features of the zinc erbium tellurite glasses as a function of doped Ag2O content. The mechanical features are estimated for the examined glasses by utilizing the Makishima-Makinzie model. The results showed the mechanical moduli of Young (E), bulk (B), Shear (K), and longitudinal (L) increased with the increment of the Ag2O substitution ratio. Besides, the radiation shielding properties were also studied and discussed. Among the shielding parameters, the linear attenuation coefficient (LAC), half-value layer (HVL), the lead equivalent and transmission rate (TR) were estimated. The linear attenuation coefficient results illustrated that the TZEAg glasses are better compared to the commercial marketing glasses, especially TZEAg5 glasses. Doping of Ag2O content in zinc erbium tellurite glass improves its ability to attenuate the gamma photons. Also, this study revealed the effectiveness of the examined glasses on the fast neutron, where the fast neutron mass removal cross-section ∑R (cm2/g) computed theoretically. The results offered the maximum value of ∑R = 0.019 cm2/g attained for TZEAg1 while the minimum value ∑R = 0.01884 cm2/g for TZEAg5 glass.

“…Tellurium oxide based glasses have attracted a strong interest over recent years due to their low phonon energy, good transmission at visible and infrared wavelength from ~0.4 to ~6 µm, high resistance to humidity and enhanced non-linear optical properties [1][2][3][4][5][6]. However, compared to other oxide glass systems, for example, silicate or germanate glass systems, tellurite glasses generally present low glass transition temperature (Tg) and onset of crystallisation temperature (Tx) causing their poor thermal stability, which can be a drawback.…”
