摘　　要：用两种不同的键合方式,即先聚合再络合(先合成丙烯酸-甲基丙烯酸甲酯共聚物,再将铕离子(Eu3+)引入此共聚物)和先络合再聚合(先合成丙烯酸铕,再合成丙烯酸铕-甲基丙烯酸甲酯共聚物)的方式将稀土元素Eu引入到高分子基体中。采用红外光谱、X射线衍射和DSC等手段对其结构、物相和热性能进行表征,确定铕与高分子基质发生配位。荧光光谱表明得到的配位聚合物是一种良好的光致发光材料,在紫外光下发出高亮度、单色性的特征红光。Photoluminescence polymer fluorescent materials containing europium complex were prepared by two different methods. One is synthesizing acryl acid-methacrylate copolymer(AA-MMA) first then introducing Eu3^+ to the copolymer. The other is synthesizing Eu(AA)_3 first then copolymerizing Eu(AA)_3-MMA. The structure, phase and thermal property were characterized using FT-IR, X-ray diffractmeter and DSC techniques. Coordination was happened between europium and polymer matrix. The fluorescence spectra demonstrated that these complexes are a series of good photoluminescence materials. Characteristic red fluorescence with high brightness and good single-color property was emitted under ultraviolet ray excitation.
