Comparative study of structural and optical analysis of Mg/Zn-ferrite by co-precipitation Available to Purchase

Comparatively investigating the structural and optical properties of nanocrystalline spinel MgFe₂O₄ and ZnFe₂O₄ developed utilizing a unique co-precipitation method is the aim of this work. The development of pure spinel structures absent of any secondary phases is confirmed by X-ray diffraction analysis. Fourier transform-infrared spectra show two vibrational bands at approximately 600 (υ1) and 400 (υ2) cm⁻¹ indicating that the cations have been redistributed in the tetrahedral and octahedral sites. The synthesized ferrites' approximately spherical nanocrystalline nature was confirmed by field emission-scanning electron microscopy. Also UV–visible (UV–vis) and photoluminescence (PL) spectroscopy were used to examine optical characteristics. Absorption peaks found by UV–vis analysis were used to calculate the optical band gaps of MgFe₂O₄ and ZnFe₂O₄. Two noticeable emission peaks in PL spectra are ascribed to oxygen vacancies and interstitial defects. The impact of the divalent cation (Mg²⁺ vs. Zn²⁺) on the structural and optical behaviour of spinel ferrites is highlighted in this comparative investigation, which is important for customizing their properties for various applications.
