Abstract

A borosilicate glass composite (SiO2—Na2CO3—ZnO—H3BO3) doped with varying concentrations of Yb2O3 (0–0.1 mol%) was fabricated using the melt-quenching technique. The thermoluminescence (TL) properties of the prepared composite were investigated, revealing that the highest TL response (the total area under the curve) was achieved with 0.06 mol% Yb2O3. Subsequently, a comprehensive dosimetric analysis, considering annealing conditions, dose–response relationship, minimum detectable dose, reproducibility of the TL response, and thermal and optical fading of the prepared glass, was determined. The obtained results demonstrated that this glass composite exhibited a linear dose–response across a wide gamma dose range of 0.5–2 kGy and about 28% TL fading after 24 h of irradiation, followed by 16% after 7 days without any further deterioration during around 1 month of examination. These advantageous properties suggest that radiation detection applications can use this examined glass composite.

辐射剂量测定用硼硅酸镱玻璃的制备及其热释光特性
采用熔融淬火技术制备了掺杂不同浓度Yb2O3 (0-0.1 mol%)的硼硅酸盐玻璃复合材料(SiO2-Na2CO3-ZnO-H3BO3)。对制备的复合材料的热释光性能进行了研究,结果表明,当添加0.06 mol%的Yb2O3时,其热释光响应(曲线下总面积)达到最高。随后,综合考虑退火条件、剂量-响应关系、最小可检测剂量、TL响应的再现性以及所制备玻璃的热光学衰落,进行了全面的剂量学分析。结果表明,该玻璃复合材料在0.5-2 kGy的宽γ剂量范围内表现出线性剂量响应,辐照24 h后TL衰减约28%,7天后TL衰减约16%,在大约1个月的检查中没有进一步恶化。这些有利的性质表明,辐射检测应用可以使用这种检测过的玻璃复合材料。
