| 摘 要： | 采用溶胶-凝胶法制得了甲基丙烯酸丁酯(BMA)-丙烯酸铕(Eu(AA)3)聚物/TiO2-S iO2杂化膜,并用FT-IR、热重分析、荧光光谱及膜综合性能测试对杂化膜的性能进行表征。研究发现TiO2可以增强杂化膜的荧光性质,在Ti∶S i摩尔比为0.2时,薄膜荧光强度可以增大约5倍。

| Abstract: | Hybrid films were prepared by copolymerization of europium acrylate and butyl methacrylate using TiO_2-SiO_2 sol as addition agent.They were characterized by FT-IR,TGA and fluorescence spectrametry.The hybrid films showed high intensity of fluorescence and increased with the increasing of the content of europium acrylate without concentration quench.TiO_2 could increase the fluorescence intensity of the films obviously with about 5 times. |
