Abstract: A europium-o-phthalic acid luminescent chelate was synthesized in liquid phase. The element analyses, the chemical analysis and FTIR results show that the chelate is Eu2L3.6H2O. The thermal analyses indicate that the chelate has better stability under the temperature of 472 ℃. The XRD pattern shows that the chelate is a crystal. The SEMphotograph shows that the chelate is in block shape and the grain size is 10~20 μm. The PL spectra show that the chelate emits the character fluorescence of Eu underultraviolet light.

Key words: Eu(Ⅲ), o-phthalic acid, fluorescence, chelate
