摘 要：<正>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.
