Investigation of the elastic moduli, optical characteristics, and ionizing radiation attenuation capacity of specific strontium borosilicate glasses

Abstract

This study aims to investigate a specific strontium borosilicate with the form 30SiO2– 40B2O3– 30SrO– xEu2O3 (x = 0.1, 0.3, 0.4, 0.5, and 0.6 mol%) glasses encoded as (GE0.1-GE-0.6) in terms of their nonlinear/linear optical, mechanical characteristics as well as gamma photons attenuation capacity. The molar refractivity (Rmolar) was possessed the values 19.409, 19.440, 19.256, 19.575, and 19.819 (cm3/mol), while the molar polarizability (αmolar) was possessed the values 7.702, 7.714, 7.641, 7.768, and 7.863, (cm3) for GE0.1, GE.0.3, GE0.4, GE0.5, and GE0.6 glasses, respectively. Values of the optical susceptibility (χ3) were 4.000 × 10−12, 4.534 × 10−12, 4.640 × 10−12, 4.749 × 10−12, and 5.095 × 10−12 (esu), and values of nonlinear refractive index (n2optical) were 6.196 × 10−11, 6.931 × 10−11, 7.075 × 10−11, 7.224 × 10−11, and 7.695 × 10−11 for GE0.1, GE.0.3, GE0.4, GE0.5, and GE0.6 glasses, respectively. The mass attenuation coefficient (µm) values were obeyed the trend: (µm)GE0.6 > (µm) GE0.5 > (µm)GE0.4 > (µm) GE0.3 > (µm) GE0.1. The half value layer (T1/2) values of 0.192 cm, 0.178 cm, 0.171 cm, 0.167 cm, and 0.164 cm were recorded for GE0.1, GE0.3, GE0.4, GE0.5, and GE0.6 samples at 0.06 MeV photon energy, respectively. The findings indicated that GE0.6 had the lowest values of mean free path (λ) and the highest effective atomic numbers (Zeff) at the photon energies investigated. The GE0.1 sample was reported the maximum exposure and energy absorption buildup factors (EBF and EABF) values, while the minimum values were reported for the GE0.6 sample. © 2022, The Author(s) under exclusive licence to Australian Ceramic Society.
