Synthesis of trimetallic oxide (Fe2O3–MgO–CuO) nanocomposites and evaluation of their structural and optical properties

Abstract

In this paper, tri-phase Fe₂O₃-MgO-CuO nanocomposites (NCs) and pure CuO, Fe₂O₃ and MgO nanoparticles (NPs) were prepared using sol-gel technique. The physical properties of the prepared products were examined using SEM, XRD, and UV-visible. The XRD data indicated the formation of pure CuO, Fe₂O₃ and MgO NPs, as well as nanocomposite formation with Fe₂O₃ (cubic), MgO (cubic), and CuO (monoclinic). The crystallite size of all the prepared samples was calculated via Scherrer's formula. The energy bandgap of CuO, Fe₂O₃ and MgO and Fe₂O₃-MgO-CuO NCs were computed from UV-visible spectroscopy as following 2.13, 2.29, 5.43 and 2.96 eV, respectively. The results showed that Fe₂O₃-MgO-CuO NCs is an alternative material for a wide range of applications as optoelectronics devices due to their outstanding properties.
