The use of phosphate-based thermoluminescence dosimeter (TLD) materials in current scenarios is presented here, particularly for the field of low dosimetry. TLD materials are currently researched for their use in for example environmental dosimetry, personal dosimetry, and medical dosimetry. There are several TLD materials available such as: sulphates, borates, fluorides, and sulphides, including some metal oxides and perovskites, which are the most used and have been widely explored. In the present scenario, new interest is being focused on the need for thermoluminescent materials for application in material science and radiation dosimetry for low-dose dosimetry. These doped TLDs are prepared using different techniques including solid-state reaction methods, combustion methods, wet chemical methods, and sol gel methods. Therefore, among the above stated TLDs, phosphates have opened a new door in radiation dosimetry, particularly in low-dose dosimetry over the last few years. This paper mainly deals with a review of various phosphate-based TLD materials and recent advancements in phosphates for TL dosimetry.
本文主要介绍了目前在低剂量辐射计量学领域中，使用基于磷酸盐的热释光剂量计（TLD）材料的情况。TLD 材料目前被广泛应用于环境剂量学、个人剂量学和医学剂量学等领域。目前有多种 TLD 材料可供选择，例如硫酸盐、硼酸盐、氟化物和硫化物，以及一些金属氧化物和钙钛矿，其中最常用和广泛研究的是这些材料。在当前的情况下，人们对新型热释光材料的需求越来越大，这些材料可应用于材料科学和辐射剂量学领域，用于低剂量辐射计量学。这些掺杂 TLD 是通过不同的技术制备的，包括固态反应法、燃烧法、湿化学法和溶胶凝胶法。因此，在上述 TLD 中，磷酸盐在过去几年中为辐射剂量学，特别是低剂量辐射计量学开辟了新的途径。本文主要综述了各种基于磷酸盐的 TLD 材料以及近年来在磷酸盐 TL 剂量学方面的最新进展。
