Abstract

This study presents the successful synthesis of Dy and Na co-doped polycrystalline MgB₄O₇ phosphor via solid-state synthesis, followed by its thermoluminescence (TL) characterization after β-irradiation. The crystal structure of the synthesized phosphor was confirmed through X-ray diffraction (XRD) analysis. The vibrational frequencies of the atomic/ionic bonds in the crystal lattice were examined using Fourier Transform Infrared (FT-IR) spectroscopy, while Scanning Electron Microscopy (SEM) was employed to investigate the morphological features of the MgB₄O₇:Dy,Na compound. Transmission Electron Microscopy (TEM) analysis was conducted to observe the structural characteristics and homogeneity in MgB₄O₇:Dy,Na. Furthermore, the thermoluminescence behavior of the phosphor was thoroughly assessed, revealing a TL glow curve comprising at least four distinct peaks, with the main dosimetric peak observed at approximately 200 °C. Repeatability and fading analyses indicate that this phosphor holds significant potential for application in radiation dosimetry under β-irradiation.

共掺 Dy 和 Na 的 β 辐照 MgB4O7 荧光粉的合成与热释光表征

本研究通过固态合成法成功合成了掺钕和掺钕的多晶 MgB₄O₇荧光粉，并对其进行了β辐照后的热致发光（TL）表征。通过 X 射线衍射（XRD）分析确认了合成荧光粉的晶体结构。傅立叶变换红外光谱（FT-IR）检测了晶格中原子/离子键的振动频率，扫描电子显微镜（SEM）研究了 MgB₄O₇：Dy,Na 化合物的形态特征。透射电子显微镜（TEM）分析观察了 MgB₄O₇：Dy,Na 的结构特征和均匀性。此外，还对荧光粉的热致发光行为进行了全面评估，发现其 TL 辉光曲线至少包含四个不同的峰值，主剂量峰在约 200 °C 时出现。可重复性和衰减分析表明，这种荧光粉在 β 辐照下的辐射剂量测定中具有巨大的应用潜力。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
