英文摘要	High-temperature resistant rare earth complexes Tb(4-FBA)3·2H2O and Tb(4-ClBA)3·2H2O were synthesized using 4-halogenated benzoic acids (4-fluorobenzoicacid and 4-chlorobenzoicacid) as ligands, respectively. They were characterized by the UV-spectra and fluorescent spectra and were compared with Tb(4-BrBA)3, which was synthesized by previous work. The UV spectra revealed that absorption intensities of the three kinds of terbium complexes Tb(4-FBA)3·2H2O, Tb(4-ClBA)3·2H2O and Tb(4-BrBA)3 in turn increased with the same molar concentration. The fluorescent spectra showed that the fluorescent intensity of Tb(4-ClBA)3·2H2O was the strongest. The relationship among energy level of the ligands, the ability of complexes absorbing UV energy and the non-radiative transitions was investigated for the experimental results. The thermal analysis indicated that Tb(4-FBA)3·2H2O and Tb(4-ClBA)3·2H2O started to lose weight around 100 ??C, suggesting the decomposition of crystal water and adsorbed water of the complexes, and the further mass loss around 450 ??C belonged to the rapid decomposition of the complexes. When the two kinds of complexes placed in a muffle furnace were heated at 350 ??C for 1 hour, it was disco-vered that the strongest fluorescence intensity of the Tb(4-FBA)3·2H2O reduced by 24% and Tb(4-ClBA)3·2H2O reduced by 13%. The IR spectra of the two kinds of complexes after heated showed that they did not decompose at high temperature.; EI; 0; 1; 54-60; 34
