Abstract
A series of Eu 3+ (La 3+ ) complexes of phen and p phthalic acid were synthesized respectively. Their IR absorption spectra, UV absorption and fluorescence spectra were studied. The results show that the oxygen atoms from p phthalic acid and nitrogen atoms from phen coordinate to the rare earth ions in the complexes. The fluorescence emission of Eu 3+ ion can be greatly enhanced, if some of the europium ions in the complexes were substituted by lanthanum ions.
