Sonochemical Synthesis of Amorphous Yttrium Iron Oxides Embedded in Acetate Matrix and their Controlled Thermal Crystallization toward Garnet (Y3Fe5O12) and Perovskite (YFeO3) Nanostructures

Original language description

Sonolysis of stoichiometric mixtures of tris(2,4 pentanedionato)iron, Fe(acac)3, and tris(2,4-pentanedionato) yttrium, Y(acac)3(H2O)3, under Ar atmosphere in tetraglyme led to a colloidal solution from which amorphous Y-Fe-O nanopowders could be precipitated by hexane. These powders are composed of amorphous nanoparticles (3 nm) of yttrium iron(III) oxide embedded in an acetate matrix as proved by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), mass spectrometry, and Mossbauer and IR spectroscopy. The thermally induced crystallization of the amorphous Y-Fe-O nanoparticles was studied by thermal analysis (TG/ DSC), evolved gas analysis (EGA), high-temperature XRD, and Mossbauer spectroscopy. Dependingon the Y/Fe starting stoichiometric ratio in the sonicated reaction mixture, the single-phase YFeO3 (YIP) with the perovskite structure or Y3Fe5O12 (YIG) with the garnet structure can be synthesized by such controlled thermal transformat
