含钐金属有机配合物的合成及其荧光性能的研究

Containing Samarium Metal Complexes Organic Synthesis and Fluorescence Properties

摘要:

以廉价的非荧光稀土离子镧掺杂钐作为中心离子，价廉易得的甲基丙烯酸甲酯(MMA)，1,10-邻菲洛林(Phen)、水杨酸(SA)为配体反应生成一系列新的四元配合物SmL*L2Phen(L*=MMA，L=SA)。通过元素分析、X-衍射分析、电镜、红外光谱、紫外光谱和荧光光谱对配合物进行了分析和表征。实验结果表明：稀土离子La的掺入能改变Sm的红光发光强度,在70%(质量分数)含量时达到最佳。Sm-La系列有机配合物的特征发射峰位于582、616和662 nm处,与植物叶绿素光合作用的吸收红光波段吻合性较好。

Abstract:

a certain proportion of new solid quaternary complexes SmL*L2Phen(L*=MMA,L=SA) of europium adulterated by cheap non-fluorescence lanthanum with the ligands of the cheap and popular methylmethacrylate (MAA), Salicylic Acid(SA) and 1, 10- phenanthroline (Phen). The complexes were characterized by elementary analysis,X-diffraction analysis,FTIR, Electron microscopy and fluorescence analysis. The results show that：Properties of the product was discussed when the mixing amount of La varied. the best result was achieved when the proper amount of La can streng then the red light luminescence of Sm, which comes to the best when mixing amount reaches 70%(mole proportion) Furthermore, the most in fluorescence emission peak of this series of complexeswas at585 nm,616 nm, 662 nm, which was most closed to the photosynthesis spectra ofvegetables.
