英文摘要	four europium trifluoroacetate complexes, eu(cf3coo)(3)center dot bpy(bpy=2,2'-bipyridine)(1), eu(cf3coo)(3)center dot phen(phen=1,10-phenanthroline)(2), eu(cf3coo)(3)center dot 2bp(bp=benzophenone)(3) and eu(cf3coo)(3)center dot 2tppo(tppo=triphenylphosphine oxide)(4) were synthesized and characterized by elemental analysis, fourier transform infrared(ftir) spectroscopy, photoluminescence(pl) spectroscopy and thermogravimetric analysis(tga). the pl spectra of the complexes at room temperature show the strong typical eu3+ ion red emission, due to the efficient energy "antenna absorption" of ligands and transitions of eu3+ ion between d-5(0)-> f-7(j(j=0-4)). the long lifetime and high quantum yield reflect that the multiphonon relaxations by coupling to o-h and c-h vibrations were reduced. according to the photoluminescent spectra, the judd-ofelt parameters omega(2) and omega(4) of the complexes were calculated and the radiative properties were also presented. the d-5(0) radiative lifetime, quantum yield and the stimulated emission cross-section of the complexes are excellent, which prove that they have promising optical properties for liquid laser. the thermal analyses indicate that they are quite stable to heat.
