Abstract

The work presented focuses on the dependence of structural, optical, magnetic, and electrical properties of ZnFe₂O₄/Graphene Oxide (GO)nanocomposites on GO concentration. The pure ZnFe₂O₄ nanoparticles and graphene oxide were synthesized using the hydrothermal method and modified Hummer’s method respectively. The ZnFe₂O₄ /GO nanocomposites with GO percentages of 1.6 %, 2.5 %, and 3.6 % were prepared by adding 50 mg, 75 mg, and 100 mg of graphene oxide to zinc ferrite hydrothermal precursor. The structural investigations were done using X-ray diffraction (XRD), and Raman spectroscopy. The morphology of ZnFe₂O₄ nano-powders and ZnFe₂O₄ /GO nanocomposites were investigated using a scanning electron microscope. The energy band gap values of pure zinc ferrite and the nanocomposites were determined using UV–Vis spectroscopy. The magnetic and electrical property dependence on GO concentration was also investigated. Notably, observed alterations in electrical properties with increasing graphene oxide content, indicated that these nanocomposites may be used in electromagnetic interference shielding or sensor devices.

ZnFe2O4/GO纳米复合材料的结构、光学、磁性和电学性能研究

本文主要研究了氧化石墨烯（GO）纳米复合材料的结构、光学、磁性和电学性能与氧化石墨烯浓度的关系。采用水热法和改进的Hummer法分别合成了纯ZnFe2O4纳米粒子和氧化石墨烯。在铁酸锌水热前驱体中分别添加50 mg、75 mg和100 mg氧化石墨烯，制备了氧化石墨烯含量分别为1.6%、2.5%和3.6%的纳米复合材料。利用x射线衍射（XRD）和拉曼光谱对其结构进行了研究。利用扫描电镜研究了纳米ZnFe2O4粉末和氧化石墨烯纳米复合材料的形貌。采用紫外可见光谱法测定了纯铁氧体锌和纳米复合材料的能带值。研究了氧化石墨烯浓度对材料磁性和电性能的影响。值得注意的是，随着氧化石墨烯含量的增加，观察到的电学性能的变化表明，这些纳米复合材料可以用于电磁干扰屏蔽或传感器器件。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
