Abstract

This study explores the influence of gamma radiation on the optical properties of PMMA composites doped with aluminum (Al) at varying concentrations. The composites were irradiated with gamma doses of 50, 100, and 200 Gy, and their optical responses were systematically analyzed using UV–Vis spectroscopy. The results reveal a pronounced dependence of both the absorption coefficient and optical band gap on the Al doping level and radiation dose. Notably, increased Al content and higher radiation exposure enhance the material’s absorption capacity while concurrently reducing the optical band gap, indicative of significant alterations in the electronic structure.

伽马辐射对不同铝浓度 PMMA 复合材料光学特性的影响

本研究探讨了伽马辐射对不同浓度掺铝（Al）的 PMMA 复合材料光学特性的影响。复合材料分别接受了 50、100 和 200 Gy 的伽马射线辐照，并使用紫外可见光谱系统分析了它们的光学响应。结果表明，吸收系数和光带隙都明显取决于铝的掺杂水平和辐射剂量。值得注意的是，铝含量的增加和辐射剂量的增加会增强材料的吸收能力，同时降低光带隙，这表明电子结构发生了重大变化。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
