摘要

Abstract

A novel kind of ligand free aurum nanoparticles (Au NPs)/poly(p-phenylene-vinylene) (PPV) composites was prepared via a simple approach. Although there were no ligands coating on the surface of the Au NPs

the Au NPs/PPV precursor composite exhibited excellent stability that no obvious variance was found as long as 6 months at ~4 ℃ in aqueous and alcohol mixed solutions. This was attributed to the strong interaction between Au NPs and PPV precursor

which was further strengthened after heat transformation. Fourier transform infrared (FTIR) and Raman spectra showed the interaction between benzene ring in PPV and Au NPs led to the part transformation of the sp

hybrid orbital into the sp

one during the composite formation. As a result

the photoluminescence (PL) life time of PPV in the composite was longer than that of pure PPV. The Au NPs/PPV composite exhibited good photo-electric response

indicating their potential application in the area of the photoelectric conversion devices.
