Characterization of ZnFe₂O₄ nanoparticles obtained by the thermal decomposition of ZnFe₂(cin)₃(N₂H₄)₃

ZnFe₂O₄ nanoparticles have been obtained from the inorganic precursor ZnFe₂(cin)₃(N₂H₄)₃ via thermal decomposition route. The precursor prepared by a simple precipitation method, was characterised by hydrazine and metal analyses, infrared spectral analysis and thermo gravimetric analysis. Using appropriate annealing conditions, ZnFe₂O₄ nanoparticles of average size around 9 nm were synthesised by the thermal treatment of the precursor. The nanoparticles were characterised for their size and structure using X-Ray Diffraction (XRD), High Resolution Transmission Electron Microscopic (HRTEM), Selected Area Electron Diffraction (SAED) and Scanning Electron Microscopic (SEM) techniques.
