[Synthesis and spectral characterization of rare-earth-ortho-amino phenylbenzoate-2,2'-bipyridine complexes].
The solid rare-earth complexes were synthesized using rare-earth ions (RE=Tb, Nd, Sm, La) reacting with ortho-amino phenylbenzoic acid (L) and 2,2'-bipyridine (bipy). Their compositions were confirmed and the spectral properties were characterized by element analysis, infrared and ultraviolet absorption spectra, and DTA-TGA. The fluorescent properties of complexes TbL3 and TbL3 x bipy x 3H2O were also measured and discussed. The result shows that the fluorescence intensity of TbL3 x bipy 3H2O is stronger than that of TbL3.
