Abstract

Lithium tetraborate (Li₂B₄O₇) was synthesized using the precipitation-aided high-temperature solid state technique followed by heating at various sintering temperatures. Then, Li₂B₄O₇ was doped with Mn using several concentrations to find the optimum composition. Manganese-doped lithium tetraborate (Li₂B₄O₇: Mn) was characterized using XRD, SEM, and TL techniques. Li₂B₄O₇: Mn was irradiated using Sr-90 at several irradiation doses to investigate how the material responded to the β radiation. Based on this experiment, the TL dose response is linear for the absorbed dose from 10 to 30 mGy. Such a feature makes this synthesized material a promising material for dosimetry applications.

暴露于β辐射的掺锰 Li2B4O7 的热致发光研究与表征

利用沉淀辅助高温固态技术合成了四硼酸锂（Li2B4O7），然后在不同的烧结温度下加热。然后，用不同浓度的锰掺杂四硼酸锂（Li2B4O7），以找到最佳成分。锰掺杂的四硼酸锂（Li2B4O7：Mn）采用 XRD、SEM 和 TL 技术进行了表征。使用 Sr-90 对 Li2B4O7: Mn 进行了几种辐照剂量的辐照，以研究材料对 β 辐射的反应。根据该实验，在吸收剂量为 10 至 30 mGy 时，TL 剂量响应是线性的。这一特点使得这种合成材料在剂量测定应用中大有可为。

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.
