Green synthesis, analysis and characterization of XZnFe₂O₃ (X=Mg,Co,Ni) quaternary alloys nanoparticles and their potential application for optoelectronics and antibacterial

Green technique or chemical co-precipitation technique has been employed to synthesize the MgZnFe2O3, CoZnFe2O3 and NiZnFe2O3 quaternary alloys nanoparticles. The structural properties are investigated by X-ray diffraction (XRD) to determine structural parameters and crystallite size. XRD peaks index numbers and intensities are varied with the atomic number. The study of morphology for the mentioned quaternary alloys nanoparticles is analyzed by scanning electron microscopy (SEM) to measure the grain size. The optical properties are investigated via ultraviolet-visible (UV-vis) and Fourier-transform infrared spectroscopy (FTIR) to reveal the changing of absorption, transmission, reflection and bandgap as the atomic number changes for verifying optical dielectric constant and refractive index models. The obtained results suggest that MgZnFe2O3, CoZnFe2O3 and NiZnFe2O3 quaternary alloys nanoparticles are very suitable for potential application in optoelectronics and antibacterial treatment.
