Abstract

This study investigates the impact of gamma irradiation on the structural, morphological, and optical properties of PLA/MnFe₂O₃/ZnO nanocomposite films. Nanocomposites were fabricated using a sol-gel method and exposed to varying gamma radiation doses. Characterization techniques, including XRD, EDX, FTIR, EPR, UV–Vis spectroscopy, and EELS, were employed to elucidate the effects of irradiation. Gamma irradiation induced significant structural modifications, such as a reduction in crystallite size (from 15 nm to 8 nm at 150 kGy) and lattice strain. The PLA matrix underwent chain scission and crosslinking, altering the material's properties. The optical bandgap narrowed from 3.2 eV to 2.8 eV at 100 kGy, leading to increased light absorption and changes in refractive index and extinction coefficient. The tunable light response, evidenced by changes in optical conductivity and electron energy loss, offers potential applications in optoelectronic devices. Gamma irradiation emerges as a versatile tool for tailoring the properties of PLA/MnFe₂O₃/ZnO nanocomposite films. The findings pave the way for the development of novel nanocomposite-based materials with tailored optical, electronic, and magnetic properties.

辐照对PLA/MnFe2O3/ZnO纳米复合材料结构、形貌和光学性能的影响

研究了γ辐照对PLA/MnFe₂O₃/ZnO纳米复合薄膜结构、形貌和光学性能的影响。纳米复合材料采用溶胶-凝胶法制备，并暴露在不同的伽马辐射剂量下。采用XRD、EDX、FTIR、EPR、UV-Vis、EELS等表征技术对辐照效果进行了分析。伽马辐照引起了显著的结构改变，如晶体尺寸减小（在150 kGy时从15 nm减小到8 nm）和晶格应变。PLA基体发生了链断裂和交联，改变了材料的性能。在100 kGy下，光带隙从3.2 eV缩小到2.8 eV，导致光吸收增加，折射率和消光系数发生变化。光导率和电子能量损失的变化证明了可调谐的光响应，在光电器件中提供了潜在的应用。伽马辐射作为一种通用的工具出现，用于定制PLA/MnFe₂O₃/ZnO纳米复合薄膜的性能。这一发现为开发具有定制光学、电子和磁性质的新型纳米复合材料铺平了道路。

期刊介绍： Reviews in Physics is a gold open access Journal, publishing review papers on topics in all areas of (applied) physics. The journal provides a platform for researchers who wish to summarize a field of physics research and share this work as widely as possible. The published papers provide an overview of the main developments on a particular topic, with an emphasis on recent developments, and sketch an outlook on future developments. The journal focuses on short review papers (max 15 pages) and these are freely available after publication. All submitted manuscripts are fully peer-reviewed and after acceptance a publication fee is charged to cover all editorial, production, and archiving costs.
