Abstract

In this study, Tb³⁺-doped MgO-Al₂O₃-B₂O₃ glasses were prepared using the melt-quenching method as potential candidates for dosimetric applications. The fabricated glass samples exhibited photoluminescence (PL) and thermally stimulated luminescence (TSL) peaks at approximately 490, 545, 590, and 620 nm, attributed to the 4f–4f transitions of Tb³⁺. The PL quantum yields increased with Tb³⁺ concentration, reaching a maximum of 92 % for the 10 % Tb³⁺-doped sample. The PL lifetimes ranged from approximately 1.9 to 2.6 ms. Based on the TSL glow curves and spectra, the 1 % Tb³⁺-doped sample showed the highest TSL intensity and exhibited good linearity over the dose range of 0.1–1000 mGy.

掺铽铝酸镁玻璃的热激发发光特性评价

在这项研究中，Tb3+掺杂的MgO-Al2O3-B2O3玻璃采用熔融淬火方法制备，作为潜在的候选剂量学应用。由于Tb3+的4f-4f跃迁，制备的玻璃样品在大约490、545、590和620 nm处表现出光致发光（PL）和热激发发光（TSL）峰。PL量子产率随Tb3+浓度的增加而增加，10% Tb3+掺杂样品的量子产率达到92%的最大值。PL的寿命大约在1.9到2.6毫秒之间。根据TSL发光曲线和光谱分析，Tb3+掺杂浓度为1%的样品TSL强度最高，且在0.1 ~ 1000 mGy的剂量范围内具有良好的线性关系。

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
