In this work, we report on the solid-state reaction synthesis of SrZrO phosphors, and their beta particle irradiation excited thermoluminescence (TL) characterization. X-ray diffraction data confirmed the obtention of the orthorhombic phase of SrZrO. Through computational glow curve deconvolution, the whole glow curve was resolved into six individual first order kinetics peaks. This is the first report concerning the usefulness of SrZrO as TL dosimeter. The synthesized phosphors exhibit TL emission from below 100 °C up to above 300 °C, being the most intense TL between 200 and 300 °C, as well as a remarkable reproducibility of the TL response in repeated irradiation-TL readout cycles.
在本工作中，我们报道了SrZrO磷光体的固态反应合成及其β粒子辐照激发热释光（TL）特性。X射线衍射数据证实获得了SrZrO的正交相。通过计算热释光曲线去卷积，整个热释光曲线被分解为六个单独的一级动力学峰。这是关于SrZrO作为热释光剂量计用途的首次报道。合成的磷光体在低于100°C至高于300°C的温度范围内均表现出热释光发射，在200至300°C之间热释光最强，并且在重复的辐照-热释光读出循环中热释光响应具有显著的可重复性。
