摘要：

Eu(Ⅲ)-Pyromellitic acid[PMA]-1, 10-phenanthroline (phen) ternary luminescent complex was prepared in ethanol and water mixed solvent. The elemental analysis, inductively coupled plasma-atomic emission spectroscopy (ICP-AES) fourier-transform infrared spectroscopy (FT-IR) indicates that its chemical constitution is Eu4( PMA)3( phen)0.75·7H2O. TG-DTA curves indicated that the complex is heat stable at the temperature of 430℃. The XRD patterns showed that the complex is a new crystal different from the two ligands’ structures. SEM image indicates that the complex is in block shape and disperses well. Photoluminescence (PL) analysis indicates that the complex emits Eu3+ characteristic luminescence under ultraviolet excitation.
