In this study, ZnO@Fe3O4composite nanostructures were synthesized using the hydrothermal method. X-ray diffraction analysis was performed for the structural characterization of nanostructures obtained with the addition of Fe3O4at different ratios, and no impurity peaks were found. Scanning electron microscope (SEM) and transmission electron microscope (TEM) were used for morphological imaging. It was understood that ZnO nanoparticles were decorated around Fe3O4in the morphology of nanostructures. Fe, Zn, and O peaks were detected in elemental analysis. Energy band gaps of ZnO@Fe3O4nanocomposite structures were obtained from absorbance data collected by use of UV-VIS spectrometer. The band gap values of nanostructures were calculated to be in the range of 2-2.1 eV. Magnetic properties were determined using a vibrating sample magnetometer (VSM), and the values of 3.76 emu/g and 7.96 emu/g were found depending on the Fe3O4content. Although these values show a limited ferromagnetic property, they are important in optoelectronic and medical imaging applications due to the advanced optical and electronic properties of ZnO.
