Synthesis of trimetallic oxide (Fe(2)O(3)–MgO–CuO) nanocomposites and evaluation of their structural and optical properties

In this paper, tri-phase Fe(2)O(3)–MgO–CuO nanocomposites (NCs) and pure CuO, Fe(2)O(3) 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,...

Sumario:In this paper, tri-phase Fe(2)O(3)–MgO–CuO nanocomposites (NCs) and pure CuO, Fe(2)O(3) 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, Fe(2)O(3) and MgO NPs, as well as nanocomposite formation with Fe(2)O(3) (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, Fe(2)O(3) and MgO and Fe(2)O(3)–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 Fe(2)O(3)–MgO–CuO NCs is an alternative material for a wide range of applications as optoelectronics devices due to their outstanding properties.
