[Studies on the infrared and fluorescence spectra of europium-lanthanum-o-aminobenzoate-2,2'-dipyridyl complexes].
A series of mixed rare earth complexes of europium and lanthanum with o-aminobenzoate and 2,2-dipyridyl were synthesized by the reaction of EuCl3 and LaCl3 with o-aminobenzoate and 2,2' dipyridyl in solution. Their infrared and fluorescence spectra were investigated. The results showed that the chemical bonds have been formed between the two ligands with rare-earth ions. The fluorescence spectra excited by 343 nm UV-light indicated that the emission intensity for europium ions can be greatly enhanced if a part of europium ions in europium complexes were substituted by lanthanum ions. This paper discussed the luminance, mechanism of too.
