Lithium aluminum borate materials was made ready for dosimetric uses in radiation processes. In order to enhance the structural and dosimetric qualities, varying mole concentrations of gadolinium were added to samples of lithium aluminum borate materials. High temperature solid-state technique was used in producing the lithium aluminum borate material. The characterization of the material was archived by using Scanning electron microscope, X-ray diffractometer, thermal gravimetric evaluation, UV–vis–NIR spectrophotometer and thermoluminescence reader/irradiator in other to determine for their structural, thermal analysis, optical properties and dosimetric properties respectively. The kinetic analysis of the major glow peak yielded the activation energy. The crystalline sizes of the undoped and gadolinium-doped Li3Al3(BO3)4 materials were reported to be approximately 36.38 nm and 68.84 nm, respectively, which relies on their matching peaks at a 2θ angle of 25.79o. The grain size for the undoped and gadolinium doped lithium aluminum borate were found within a given range of values 140–160 nm, and 80–100 nm respectively. The optical energy band gap was found within 3.90 eV–4.35 eV for the gadolinium doped while the undoped is 3.00 eV for lithium aluminum borate respectively. A larger energy band gap of lithium aluminum borate was observed after gadolinium was incorporated as dopant. The phosphor of lithium aluminum borate doped with gadolinium was observed to exhibit prominent TL intensity peaks at 100 °C following irradiation. The irradiated samples of lithium aluminum borate doped with gadolinium showed a dose response that was linear between 20 and 150 Gy. This work demonstrates the potential use of Gd-doped lithium aluminum borate phosphor in radiation dosimetry.

合成钆掺杂硼酸铝锂 [Li3Al3（BO3）4：Gd] 材料，并表征其结构、光学和热发光特性，用于剂量学应用


硼酸铝锂材料已准备好用于辐射过程中的剂量学。为了提高结构和剂量学质量，向硼酸铝锂材料样品中添加了不同摩尔浓度的钆。高温固态技术用于生产硼酸铝锂材料。通过使用扫描电子显微镜、X 射线衍射仪、热重评估、UV-vis-NIR 分光光度计和热释光读取器/辐照器对材料的表征进行存档，以分别确定它们的结构、热分析、光学特性和剂量学特性。主要辉光峰的动力学分析产生了活化能。据报道，未掺杂和钆掺杂的 Li3Al3（BO3）4 材料的晶体尺寸分别约为 36.38 nm 和 68.84 nm，这取决于它们在 2θ 角 25.79o 处的匹配峰。未掺杂和钆掺杂的硼酸铝锂的晶粒尺寸分别在 140-160 nm 和 80-100 nm 的给定值范围内。钆掺杂的光能带隙在 3.90 eV–4.35 eV 以内，而硼酸铝锂的未掺杂光能带隙在 3.00 eV 以内。在掺入钆作为掺杂剂后，观察到硼酸铝锂的能带间隙更大。观察到掺杂钆的硼酸铝锂的荧光粉在照射后在 100 °C 时表现出明显的 TL 强度峰。掺杂钆的硼酸铝锂的辐照样品显示出 20 到 150 Gy 之间的剂量反应。这项工作证明了 Gd 掺杂硼酸铝锂荧光粉在辐射剂量测定中的潜在用途。
