摘　　要：利用Langmuir-Blodgett(LB)技术,以二次水为亚相,在亚相表面直接铺展掺杂有稀土配合物Eu(TTA)3phen的苯乙烯分子,然后在一定表面压下进行现场聚合,制得了发红光的聚苯乙烯超薄膜,并用红外光谱、紫外-可见光谱、透射电子显微镜、荧光显微镜、光谱型椭圆偏振仪等对薄膜进行了表征。Rare earth complex of Eu（TTA）3phen doped styrene in chloroform was spread onto the surface of water in the Langmuir-Blodgett trough.Then the blend layer was irradiated by UV lights for polymerization after the volatilization of the solvent under a certain surface pressure.A red emission thin film of polystyrene was fabricated by in-situ polymerization.The film was characterized by FTIR,UV-vis emission,transmission electron microscope,spectroscopic ellipsometer and fluorescence microscope.
