根据配位化学及中药学的研究理论，结合槲皮素稀土配合物的结构特点，将槲皮素与稀土Dy3+离子按1：1比例配合形成稳定二元体系配合物，其分子式为DyC15H8O7Cl2·6H2O。研究表明，在紫外光谱中，配合物的吸收波长分别红移了11nm和38nm；红外光谱显示槲皮素分子中1656.42 cm-1上的苯环骨架在槲皮素-Dy3+配合物中消失，表明槲皮素羰基中的氧与Dy3+发生了反应；在荧光光谱中，配合物在最大激发波长为253 nm及最大发射波长为582 nm时表现出强的荧光效应；在二元体系中加入表面活性剂（曲拉通X-100和Tween 20）形成三元配合物，当加入量为2.0 mL时，三元配合物的荧光强度分别是二元体系的荧光强度的1.5倍和2倍。

According to the theory of coordination chemistry and the study of traditional Chinese medicine, and combined with the structure characteristics of quercetin and rare earth complexes , quercetin formed a stable binary complex DyC15H8O7Cl2 containing six water molecules with rare-earth according to the proportion of 1:1. It was showed the absorption spectra of the complex occurred about 11 nm and 38 nm red shift in the ultraviolet spectrum. The absorption peak of quercetin disappeared at 1656.42 cm-1 in the infrared spectrum when binary complex formed. It was deduced that carbonyl oxygen in quercetin was reacted with Dy3+. At the same time, the quercetin-Dy3+ complexes had a strong fluorescence effect. The maximum excitation and emission wavelength is 253nm and 582nm. The binary complex further formed ternary system with surfactant (Triton X-100 and Tween 20). When the amount of surfactant was 2.0 mL, the fluorescence intensity of the ternary system was 1.5 to 2.0 times stronger than binary system.
