Preparation, Characterization of nanocrystals of YFeO3 via co-precipitation method

Yttrium iron oxides nanocrystals have been synthesized through a co-precipitation method. The precursors produced were obtained from aqueous yttrium and iron (III) chlorides mixtures and surfactant using 1.5 M sodium hydroxide at pH 8 as precipitating agent [1]. The crystallite of the single phase of YFeO3 obtained by calcinations at 800°С for 5h. The samples were characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared absorption (FT-IR) and UV–visible spectroscopy [2]. The XRD showed the orthoferrite structure of YFeO3. The size of the YFeO3 crystals is weakly dependent on the initial composition preparation procedure, and the size and shape of their agglomeratesare sensitive to the conditions of coprecipitation of the hydroxides. The FT-IR spectra confirm the characteristic peaks of YFeO3 stretching and bending vibrations. The UV-vis showed charge transfer between metals and ligand.
