π－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 od 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.
