Synthesis and Characterization of EuL3(phen) Luminescent Complex


Article Preview

The europium(III)-benzoic acid(HL)-1,10-phenanthroline(phen) complex was synthesized in the ethanol-H2O system by a precipitation method. The morphology of the minicrystal complex with diameters of ca. 1.0 µm is characterized by scanning electron microscopy (SEM). Elemental analysis and inductively coupled plasma-atomic emission spectroscopy (ICP-AES) are used to determine the chemical composition of the complex. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction analysis (XRD) are used to examine the structure of the complex. The results show that the complex is a new kind of crystalline complex and the composition of the complex is speculated to be EuL3(phen). The thermogravimetric curve (TGA) analysis indicates that the complex is stable below 232 °C in air. The photoluminescence analyses (PLA) exhibit that the complex emits the characteristic red fluorescence of Eu (III) ions at 613nm under ultraviolet light excitation.
