10BaO–20ZnO–20LiF-(50-x)B₂O₃-xSm₂O₃ (x = 0, 0.1, 0.3, 0.5, 0.7, and 1.0 mol %) glasses were synthesized with an objective to examine the γ-radiation-induced defects and Thermoluminescence (TL) characteristics towards potential TL dosimetry application. The addition of 0.1 mol % Sm₂O₃ to the host glass led to a drastic enhancement (almost two thousand times) in the TL intensity and concentration quenching was seen thereafter. The Sm₂O₃ concentration and γ-dose for the examination of defects and TL features were optimized to be 0.1 mol % and 3 kGy, respectively. The lack of distinct peaks in the X-Ray Diffraction pattern confirmed the glass amorphous nature. The structural modification after irradiation was conveyed in the optical absorption spectroscopy by the presence of color centers and in Fourier Transform Infrared spectroscopy by the increase in the Non-Bridging Oxygens. The color centers were identified as Non-Bridging Oxygen Hole Center and Boron $E’$-center from the Electron Spin Resonance characterization. The glass manifested a good linear TL response between 0.25 and 3 kGy, high sensitivity, a minimum detection dose of 2$\pm$0.2 Gy, reusability and reproducibility after annealing at 523 K for 15 min, $Z_{eff}$ of 9.6, and trap activation energies between 0.47 and 1.28 eV. The application of the titled glass system as a potential TL dosimeter is proposed for food irradiation, and γ-environment (up to 3 kGy).

合成了 10BaO–20ZnO–20LiF-(50- x )B ₂ O ₃ - x Sm ₂ O ₃ ( x  = 0、0.1、0.3、0.5、0.7和 1.0 mol %) 玻璃，目的是检查 γ-辐射诱导缺陷和热释光 (TL) 特性对潜在 TL 剂量测定应用的影响。向主体玻璃中添加 0.1 mol% Sm ₂ O ₃导致 TL 强度的显着增强（几乎 2000 倍），此后观察到浓度猝灭。Sm ₂ O ₃用于检查缺陷和 TL 特征的浓度和 γ 剂量分别优化为 0.1 mol % 和 3 kGy。X 射线衍射图中没有明显的峰证实了玻璃的无定形性质。辐照后的结构改变通过色心的存在在光学吸收光谱中传递，在傅立叶变换红外光谱中通过非桥氧的增加传递。色心被确定为非桥接氧孔中心和硼$乙\text{'}$-中心来自电子自旋共振特征。该玻璃在 0.25 到 3 kGy 之间表现出良好的线性 TL 响应，灵敏度高，最小检测剂量为 2$\pm$0.2 Gy，在 523 K 下退火 15 分钟后的可重复使用性和再现性， $Z_{\mathrm{电子}FF}$9.6，并在 0.47 和 1.28 eV 之间捕获活化能。建议将标题玻璃系统用作潜在的 TL 剂量计，用于食品辐照和 γ 环境（高达 3 kGy）。
