(TlO)-(LiO)-(BO)-(SmO) glass system with various SmO additives ( = 0, 0.2, 0.4, 0.6) was studied in detail. The vibrational modes of the (TlO)-(LiO)-(BO) network were active at three composition-related IR spectral peaks that differed from those mixed with Samarium (III) oxide at high wavenumber ranges. These glass samples show that their permeability increased with the Samarium (III) oxide content increase. Additionally, the electronic transition between localized states was observed in the samples. The MAC, HVL, and Zeff values for radiation shielding parameters were calculated in the energy range of 0.015-15 MeV using the FLUKA algorithm. In addition, EBF, EABF, and Σ values were also determined for the prepared glasses. These values indicated that the parameters for shielding (MAC, HVL, Z, EBF, EABF, and Σ) are dependent upon the Samarium (III) oxide content. Furthermore, the addition of Samarium (III) oxide to the examined glass samples greatly reinforced their shielding capacity against gamma photon. The findings of the current study were compared to analyses of the XCOM software, some concretes, and lead. In the experiment, it was found that the SMG0.6 glass sample was the strongest shield.
详细研究了添加不同含量氧化钐(SmO,SmO含量分别为0、0.2、0.4、0.6)的(TlO)-(LiO)-(BO)-(SmO)玻璃体系。(TlO)-(LiO)-(BO)网络的振动模式在三个与成分相关的红外光谱峰处表现活跃,这些峰与在高波数范围内与氧化钐(III)混合的峰不同。这些玻璃样品表明,随着氧化钐(III)含量的增加,它们的磁导率增加。此外,在样品中观察到了局域态之间的电子跃迁。使用FLUKA算法在0.015 - 15 MeV的能量范围内计算了辐射屏蔽参数的MAC、HVL和Zeff值。此外,还测定了所制备玻璃的EBF、EABF和Σ值。这些值表明屏蔽参数(MAC、HVL、Z、EBF、EABF和Σ)取决于氧化钐(III)的含量。此外,向所研究的玻璃样品中添加氧化钐(III)极大地增强了它们对伽马光子的屏蔽能力。将本研究的结果与XCOM软件、一些混凝土和铅的分析结果进行了比较。在实验中,发现SMG0.6玻璃样品是最强的屏蔽材料。
