合成了具有双氧化膦配体的发光Eu(III)配合物。通过单晶 X 射线衍射确定了新型 Eu(III) 配合物的几何结构。其中一种Eu(III)配合物显示出非常尖锐的红光发射和大的受激发射截面（半峰全宽（FWHM）=2.1nm，受激发射截面=1.80×10−20cm2）。从几何结构的对称性角度讨论了Eu(III)配合物发射带的锐度。
Luminescent Eu(III) complexes with bis-phosphine oxide ligands were synthesized. Geometric structures of novel Eu(III) complexes were determined by single-crystal X-ray diffraction. One of the Eu(III) complexes showed remarkably sharp red emission and large stimulated emission cross-section (full width at half maximum (FWHM)=2.1nm, stimulated emission cross-section=1.80×10−20cm2). The sharpness of the emission bands of the Eu(III) complexes was discussed in terms of the symmetry of the geometrical structure.
