摘要
采用乙醇-水溶液析出法合成了稀土离子RE3+(La3+,Nd3+,Gd3+,Dy3+,Y3+,Yb3+)与间硝基苯甲酸(HA)和邻菲罗啉(phen)的二元及三元固态配合物.通过元素分析、热重分析证实配合物组成为NdA3·3H2O,REA3·2H2O(RE=Gd,Dy),REA3(RE=Yb,Y)和LaA3·phen.考察了配合物的红外光谱、紫外光谱、荧光光谱和溶解性.
The solid state complexes of rare earth ions (Ⅲ) with m-nitrobenzoic acid (HA) and o-phenanthroline (phen) have been synthesised in C2H5OH solution,The composition of complexes are NdA3·3H2O,REA3·2H2O(RE=Gd、Dy),REA3(R=Y、Yb) and LaA3 phen determined by elemental analysis and thermal analysis.UV, IR and fluorescence spectra of complexes have been characterized.The results showthat the Eu3+ complex has very noticeable fluorescence intensity in 593.0 um (5Do→7F1) and 613.0 um(5Do→F2) under λex=395.0 um.
