摘要

采用熔融淬火法制备了硼酸锶玻璃体系，并对玻璃样品在600℃下进行不同时间的热处理，制备了相应的玻璃陶瓷衍生物。对制备和热处理后的样品进行FTIR分析。随着温度的升高，比体积（Vs）略有增加，而氧堆积密度（OPD）略有下降，这与寄主前体的性质、插入改性剂和热过程速率有关。研究了处理8 h后样品的热释光特性，即剂量响应线性、可重复使用性、最小可检测剂量和热衰减。采用计算和实验相结合的方法确定了发光峰的动力学参数。研究并量化了所显示的发光曲线/峰与TL测量升温速率的关系。

Thermoluminescence and structural characterization of crystalline alkali strontium borates

A strontium borate glass system was prepared by the melt-quenching method and the corresponding glass ceramic derivatives were produced by applying heat treatment (HT) on glass samples at 600 °C for different periods. FTIR analysis was carried out for the prepared and thermally treated samples. The specific volume (Vs) displayed a slight increase with HT while the oxygen packing density (OPD) revealed a slight decrease, correlating with the nature of host former, inserted modifier and rate of thermal process. The thermoluminescence (TL) properties, namely, dose response linearity, reusability, minimum detectable dose, and thermal fading, of the samples treated for 8 h were investigated. The kinetic parameters of the TL glow peaks were determined using computational and experimental methods. The dependence of the displayed glow curves/peaks on the TL measurement heating rate was investigated and quantified.
