Abstract

We evaluate the temperature effect on the X-ray radiation-induced luminescence (RIL) of differently doped silica fibers obtained via the sol-gel route. Previous investigations showed that these optical materials exhibit interesting dosimetry properties, such as very good detection capabilities and linear response over a large range of dose rate. However, several radiation environments, such as space and particle accelerators, also require a careful assessment of the temperature effect on these properties exploited for dosimetry. With this aim, we characterize their RIL efficiency and spectral dependence at several irradiation temperatures. We demonstrate that all the investigated materials present a nonnegligible temperature dependence of the RIL in the range from -120 °C to 80 °C. The temperature effect on the RIL signal is still compensable via calibration and temperature monitoring.

温度对不同掺杂硅基光纤辐射发光的影响

我们评估了温度对通过溶胶-凝胶法获得的不同掺杂二氧化硅纤维的 X 射线辐射诱导发光（RIL）的影响。以前的研究表明，这些光学材料具有有趣的剂量测定特性，如良好的检测能力和在较大剂量率范围内的线性响应。然而，在一些辐射环境中，如太空和粒子加速器，还需要仔细评估温度对这些用于剂量测定的特性的影响。为此，我们对几种辐照温度下的 RIL 效率和光谱依赖性进行了表征。结果表明，在 -120 ℃ 至 80 ℃ 的范围内，所有研究材料的 RIL 都呈现出不可忽略的温度依赖性。温度对 RIL 信号的影响仍然可以通过校准和温度监测得到补偿。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
