合成了正己酸铕、正辛酸铕、月桂酸铕和硬脂酸铕4种不同碳链链长的脂肪酸铕配合物,通过哈克转矩流变仪将铕配合物(质量分数1%)机械掺杂于3种不同透明度的聚乙烯(PE)、聚丙烯(PP)和聚苯乙烯(PS)通用树脂中,制备了系列铕配合物掺杂聚合物光致发光复合材料,考察了配体、配合物、聚合物基体对复合材料的外观、透明性及其荧光性能的影响.结果表明,4种脂肪酸铕配合物及其掺杂的复合材料在紫外光的激发下均在593、617 nm处发射强的Eu3+离子5D0→7F1、5 D0→7 F2跃迁的特征荧光;脂肪酸配体的碳链长短对铕配合物及复合材料的发光影响较小;PE、PP复合材料发光颜色与红光铕配合物相同,PS复合材料因基体PS和Eu3+离子的发光共同作用而呈现了玫瑰红的荧光发射.
