Abstract:
The binary complex of Er with terephthalic acid (1,4-benzenedicarboxylic acid, 1,4-H2bdc) was synthesized in 1∶1 ethanol/water solution under 80 ℃. The composition and optical properties of the complex were analyzed and characterized by elemental analysis (EA), Fourier transform infrared spectrosopy(FTIR), thermal analysis (DSC-TGA), UV-Vis spectroscopy(UV-Vis) and fluorescence spectroscopy(FS), respectively. The results showed that the oxygen atoms in carboxyl group of terephthalic acid was coordinated with Er3+ ions, and the complex molecular formula is Er(1,4-bdc)·2H2O. Additionally, the complex exhibits a good fluorescence property.
