摘要

研究了BaO浓度的增加对B2O3-CaO-ZnO-BaO-Er2O3玻璃样品性能的影响。观察到密度和摩尔体积的增加。FTIR分析揭示了硼酸盐单元的破坏和具有BaO含量的nbo的产生。带隙能（Eg）从3.028 eV降低到2.882 eV。BaO的加入增加了介质常数和折射率。研究了在0.015 ~ 15 MeV范围内的辐射屏蔽性能。BaE4样品具有最高的线性衰减系数（LAC）和有效原子序数（Zeff）。Zeff最大值为0.015 MeV，范围为41.54 ~ 43.85。在所有选择的能级上，BaE4样品具有最低的MFP。与其他玻璃系统的比较证实了BaE4样品对伽马射线屏蔽应用的适用性。

Impact of high BaO content on tuning the structural, optical and radiation shielding properties of multicomponent borate glasses

The impact of increasing BaO concentration on the B₂O₃-CaO-ZnO-BaO-Er₂O₃ glass samples' properties has been examined. The increase in density and molar volume is observed. FTIR analysis reveals the disruption of borate units and the creation of NBOs with BaO content. The band gap energy (E_g) decreases from 3.028 to 2.882 eV. BaO addition increases the dielectric constant and the refractive index. The radiation shielding properties were investigated from 0.015 to 15 MeV. The BaE4 sample has the highest linear attenuation coefficient (LAC) and effective atomic number (Z_eff). The maximum Z_eff is found at 0.015 MeV, ranging from 41.54 to 43.85. The BaE4 sample possesses the lowest MFP at all selected energy levels. The comparison with other glass systems confirms the suitability of the BaE4 sample for gamma ray shielding applications.

期刊介绍： In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
