采用溶胶-凝胶法制备了一系列PPV/TiO2纳米复合膜，探讨了TiO2纳米微粒对PPV发光性能的影响.研究发现，这些复合膜的发光性质依赖于TiO2／PPV的质量比，.在TiO2/PV的质量比为1／9时，复合膜中的TiO2微粒对PPV的荧光具有猝灭作用；当TiO2／PPV的质量比为1／1时，复合膜中的TiO2对PPV的荧光具有增强作用.通过FT-IR，UV-Vis，FL光谱和TEM探讨了复合膜微结构与其发光性质的关系.

A series of poly (phenylenevinylene)(PPV)/ TiO2 nanocomposites were prepared from the mixtures of PPV precursor and TiO2 sol by employing a sol-gel process. The luminescent properties of the PPV/TiO2 nanocomposites were dependent on the mass ratio of TiO2 to PPV. When the mass ratio of TiO2 to PPV was 1/9, the resultant TiO2 nanoparticle quenched the luminescence of PPV. However, when the mass ratio of TiO2 to PPV was 1/1, the PPV/TiO2 nanocomposites showed enhanced luminescence. In this paper, the relationships between the luminescent properties and structures of PPV/TiO2 nanocomposites were investigated by FT-IR, UV-Vis, FL spectra and TEM.
