合成得到一系列异核稀土双（苯基亚砜）乙烷（bphse）配合物和异核稀土双（苯基亚砜）乙烷与1，10-啡咯啉的配合物，通过元素分析、电感耦合等离子体法、电导、红外和紫外光谱对配合物进行了表征，并研究了这些配合物的固体和溶液的荧光光谱。荧光光谱说明这些配合物均有较强的荧光，其中三元配合物Eu(3+)的荧光强于二元配合物。在同系列异核配合物中Eu(3+)的荧光强度次序为：Eu－Y配合物＞Eu-Gd配合物＞Eu－Tb配合物＞Eu配合物＞Eu-La配合物。
A series of complexes of heteronuclear rare earth bis (phenylsulfoxide) ethane (bphse) and heteronuclear rare earth bis (phenylsulfoxide) ethane with 1,10-phenanthroline were synthesized and characterized by elemental analysis, The complexes were characterized by inductively coupled plasma method, conductivity, infrared and ultraviolet spectroscopy, and the fluorescence spectra of the solid and solution of these complexes were studied. Fluorescence spectra indicate that these complexes have strong fluorescence, in which the ternary Eu (3+) fluorescence is stronger than the binary complexes. The order of Eu (3+) fluorescence intensity in the same series of heteronuclear complexes is Eu-Y complex> Eu-Gd complex> Eu-Tb complex> Eu complex> Eu-La complex.
