title: [Synthesis, characterization and fluorescent property of ternary complexes of rare-earth, cinnamic acid and 2,2'-bipyridine].
abstract: The ternary rare-earth complexes were synthesized using cinnamic acid (L), 2,2'-bipyridine (bipy) and rare-earth (RE= Tb, Eu, Gd, Nd) in ethanol solution. Their compositions were confirmed to be REL3 x bipy by the element analysis, infrared and ultraviolet absorption spectra, and DTA-TGA, respectively. The spectral properties of complexes and the fluorescent property of EuL3 x bipy were discussed. The fluorescence intensity of EuL3 is 4.5 times stronger than that of EuL3 x bipy x H2O.
