摘要

研究评估了不同Bi2O3含量对Bi2O3- b2o3 - sio2 - na2o玻璃体系的影响，其中Bi2O3的加入提高了密度（ρ）和摩尔体积（Vm）。弹性模量随Vm的增大而减小。XRD光谱证实了其无定形性质。红外光谱（FTIR）和拉曼光谱（Raman spectroscopy）表明，随着Bi2O3浓度的增加，材料的振动带发生了变化，峰值强度增加。它表示由于Bi-O键的形成和非桥接氧（NBOs）的增加而引起的结构改变。研究了在0.015 MeV ~ 15 MeV范围内的辐射屏蔽性能。在0.015 MeV下，线性衰减系数（LAC）在5.851 cm−1（游离Bi2O3玻璃）和210.436 cm−1（含15 mol% Bi2O3玻璃）之间变化。在LAC中掺入Bi2O3，增强了玻璃的屏蔽能力。半值层（HVL）受Bi2O3含量的影响，在0.015 MeV时，由于添加15 mol% Bi2O3， HVL从0.118 cm降低到0.0034 cm。

Impact of varying Bi2O3 content on physical, mechanical, structural and gamma ray shielding properties of Bi2O3-B2O3-SiO2-Na2O glass system

The study evaluates varying Bi₂O₃ content's impact on the Bi₂O₃-B₂O₃-SiO₂-Na₂O glass system, where by Bi₂O₃ addition enhances the density (ρ) and molar volume (V_m). The elastic moduli decrease due to the increase in V_m. XRD spectroscopy confirms the amorphous nature. FTIR and Raman spectroscopy indicate shifts in vibrational bands and heightened peak intensities associated with Bi₂O₃ concentration. It signifies structural alterations owing to Bi-O bond formation and an increase in non-bridging oxygens (NBOs). The radiation shielding properties were investigated from 0.015 MeV to 15 MeV. The linear attenuation coefficient (LAC) at 0.015 MeV varied between 5.851 cm⁻¹ (for the free Bi₂O₃ glass) and 210.436 cm⁻¹ for the glass with 15 mol% Bi₂O₃. The LAC showed Bi₂O₃ incorporation to enhance the glasses' shielding ability. The half value layer (HVL) is affected by the Bi₂O₃ content, where the HVL at 0.015 MeV reduces from 0.118 to 0.0034 cm due to the addition of 15 mol% Bi₂O_3.
