Sonochemical Preparation of Ternary Europium Complexes Eu(DBM)3•phen
Eu(DBM)3•phen complexes have been Successfully synthesized by the sonication of an Ethanol solution of europium chloride and dibenzoylmethanide (DBM) in the presence of 1,10-phenanthroline(phen). The properties of the Eu(DBM)3•phen complexes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform Infrared spectroscopy (FT-IR) and fluorescence spectrometry (FS). Reaction conditions, such as ultrasonic power and the concentration of complexing reagent, were found to have close relation with the morphologies of final products. The formation mechanism of Eu(DBM)3•phen complexes with ultrasonic irradiation is discussed in the context.
