Abstract

Titanium Borate glasses with the composition 60B₂O₃-(20-x)BaF₂-15LiF-5TiO₂-xSm₂O₃ for various concentrations of Sm₂O₃ from 0.1 to 2.5 mol% were synthesized by conventional melt quenching method. Different spectroscopic investigations were conducted to elucidate the usefulness of the titled glasses for visible lasers and radioactive radiation shielding. The correlation of absorption spectral information with the PL spectral data (emission and decay) facilitates the estimation of various radiative properties. The covalent/ionic environment around the Sm³⁺ions was estimated using Judd-Ofelt (J-O) parameters. The key lasing parameters such as branching ratios, stimulated emission cross-section and quantum efficiencies were measured. The PL profiles recorded for the titled glasses show strong emission in reddish-orange visible region which is further confirmed by the measured CIE coordinates. A thorough theoretical investigation has also been conducted to understand the effective usages of the BaLTBSm glasses for radiative against fast neutrons and gamma rays. The gamma radiation shielding parameters, neutron attenuation and charged ions interaction properties were computed by adjusting the weight fraction of constituent elements in each of the glass samples using the densities. BaLTBSm25 glasses, especially those with higher Sm content, could be promising materials for radiation shielding applications especially in special electronic installations where sensitive components require maximum protection from gamma, neutron and charged particle interactions. The results show that BaLTBSm glasses can be used for optical and radiation shielding applications. All the aforementioned experimental as well as theoretical investigations carried on the titled glasses allows to contemplate the superior nature of BalTBSm10 and BaLTBSm25 glasses for visible reddish-orange photonic device and radiation sheilding applications.

Sm3+离子掺杂硼酸钛玻璃的结构、光学和辐射屏蔽性能研究

采用熔体淬火法制备了Sm2O3浓度在0.1 ~ 2.5 mol%范围内的60B2O3-(20-x)BaF2-15LiF-5TiO2-xSm2O3硼酸钛玻璃。进行了不同的光谱研究，以阐明标题玻璃对可见激光和放射性辐射屏蔽的有用性。吸收光谱信息与PL光谱数据（发射和衰减）的相关性有助于估计各种辐射特性。采用Judd-Ofelt （J-O）参数估计Sm3+离子周围的共价/离子环境。测量了分支比、受激发射截面和量子效率等关键激光参数。为标题玻璃记录的PL剖面显示在红橙色可见区域有强烈的发射，这进一步被测量的CIE坐标所证实。为了了解BaLTBSm玻璃对快中子和伽马射线辐射的有效使用，还进行了彻底的理论研究。通过利用密度调整各玻璃样品中组成元素的质量分数，计算了伽马辐射屏蔽参数、中子衰减和带电离子相互作用特性。BaLTBSm25玻璃，特别是那些Sm含量较高的玻璃，可能是辐射屏蔽应用的有前途的材料，特别是在特殊电子装置中，敏感元件需要最大限度地保护免受伽马，中子和带电粒子相互作用的影响。结果表明，BaLTBSm玻璃可用于光学和辐射屏蔽。所有上述的实验和理论研究都在标题玻璃上进行，允许考虑BalTBSm10和BaLTBSm25玻璃在可见红橙色光子器件和辐射屏蔽应用中的优越性质。
