摘　　要：研究了Eu(DBM)3(DiBut-bpy)/TiO2/AA单分子膜的表面压-分子面积(π-A)曲线和稳定性,单层膜中的TiO2纳米粒子是经TBT(tetrabutyloxyltitanium,钛酸四丁酯)二维溶胶-凝胶法得到的.TiO2纳米粒子和铕络合物都被成功地转移到固体基片上,得到了具有良好的机械和热稳定性的新型发光薄膜.小角度X射线衍射结果证明这种复合膜具有层状有序的周期性结构.讨论了TiO2基质对复合膜发光机理的影响.pi - A curve and stability of the monolayer of Eu(DBM)(3)(DiBut-bpy) /TiO2/AA(arachidic acid) are investigated. TiO2 nanoparticles are obtained by TBT (tetrabutyloxyltitanium) 2D sol-gel process. TiO2 nanoparticles and europium complex were transferred successively onto the solid substrate by Langmuir-Blodgett technique. A novel luminescence thin film was obtained and this film has good mechanic and thermal stability. The linear relationship of UV-visilbe spectra vs the layers of LB film indicates that this composite film is vertically homogeneous. The result of small-angle XRD further demonstrated that this composite film has ordered periodic structure. The effect of TiO2 nanoparticles on the luminescence mechanism of this composite film was discussed.
