Open publisher page 0 citations

Abstract

Thirteen solid rare earth tesnary complexes with cinnamic acid C 6H 5CH=CHCOOH, HL and o phenanthroline (phen), RE(phen)L 3 were synthesized. Their IR absorption spectra, molar conductance, TG DTA, X ray power diffraction analysis and fluorescence spectra were studied. The results show that all coordination compounds are oxidized and decomposed around 400 ℃ to 540 ℃. They are all crystalline material. The fluorescence spectra indicate that the fluorescence emission intensity of Eu(phen)L 3 is the highest among them.
