Preparation and Non-linear Optical Properties of Mesoporous Silica Film Incorporated with Gold Nanowires

doi:10.3724/SP.J.1077.2013.12782

Abstract

Abstract: An Au-loaded oriented mesoporous silica film was prepared by hot air flow method and its non-linear optical properties were investigated. Amino groups were first introduced to the oriented mesochannels’ surface based on a chemical reaction, and gold nanowires were incorporated into the oriented mesochannels via the reduction by H₂ after the interaction between the amino groups and auric chloride acid. The hybrid film presents obviously non-linear optical properties according to Z-scan measurement. The hybrid film shows anisotropy, which is consistent with the fact that the nanowires are aligned. So the film is expected to be applied in the new optical devices.

Key words: mesoporous silica film, gold nanowires, non-linear optics, orientation
