铕-苯甲酸-邻菲咯啉掺杂配合物体系的合成与荧光性能研究

The Synthesis and Fluorescence Properties of Doping Europium-Benzonic Acid-Phenanthroline Complexes

合成了Eu1-xLnx(BA)3Phen(Ln:Gd,La,Y;BA:苯甲酸;Phen:1,10-邻菲咯啉)系列固体粉末配合物。红外光谱的研究表明该系列配合物具有相似的结构;荧光光谱表明该类配合物均能发出强的铕离子的特征荧光,并且掺杂元素能增强配合物的发光性能,起到共发荧光作用。

Eu1-xLnx（BA）3Phen（Ln： Gd, La, Y; BA： benzonic acid; Phen- phenanthroline; x=0.0-0.9） complexes are synthesized, and their similar structures showed by IR spectra. Fluorescence spectra indicate that the complexes can emit intense characteristic fluorescence from europium ion and the doping elements can enhance the fluorescence intensities of central europium ion and have co-fluorescence effect.
