    Abstract

    Immobilized gold nanoparticles on a three-dimensionally ordered macroporous (3DOM) film were prepared by a dipping method. The localized surface plasmon resonance of the nanoparticles and the stop-band of the 3DOM film, both still evident after immobilization, are both dependent on the refractive index of the surrounding medium. The picture shows a 3DOM film before (left) and after (right) coating with gold nanoparticles.
