Structural, Morphological, Optical and Magnetic Properties of Undoped and Fe Doped Manganese Oxide Nanoparticles Prepared by CBD

Abstract:

In this study beads like nanoparticles of manganese oxide with different doping of iron concentrations from 2% to 10% were deposited on ultrasonically cleaned glass substrate by chemical bath deposition technique. Different analytical techniques including XRD, SEM, DRS and VSM were utilized to analyze the structure, morphology, optical and magnetic properties. XRD analysis confirms the crystallite size of Fe-MnO₂ were between 13.70 nm to 46.46 nm, morphological examination indicated that Fe-MnO₂ have cubic and beads-like structures. SEM have revealed the average grain size of 613.3 nm and non-uniform deposition of thin film, DRS analysis confirms that pure MnO has band gap energy 2.90 eV and is decreased with increasing concentration of iron i.e shifted towards lower band gap energy semiconductor materials, VSM reveals that magnetization increases with increase in iron concentration. The best properties were obtained at 6% iron doping because, with further increase in doping concentration, the structure started to distort.
