Description
Summary:Gold nanorods are fascinating nanomaterials for electro-optical applications in nanotechnology, but the basic drawbacks have been thermally unstable and the difficulty in incorporating into the film. In this study, we have developed a simple and highly-reproducible method for large-scale fabrication of composite films consisting of gold nanorods and an organic polymer. The film could be easily casted for more than 10 × 10-cm 2 area and the shape (that is, optical characteristic) of gold nanorods could withstand up to ca. 200°C. The composite film was also sensitive to the dielectric constant of the surrounding medium.
