The optical properties of Au/Ag nanoparticles coated with diamond-like carbon films
Noble metal nanoparticles have prominent surface effect, quantum size effect and active outer-shell electrons, they cause these particles to present unusual optical phenomenon, display the strong local surface plasma resonance (LSPR) effect. DLC films have good biological compatibility, good wear resistance and corrosion-resisting, it also has high transmissibility in the visible and near-infrared region. A new LSPR interface between diamond-like carbon films and the Au/Ag NPs was formed by Plasma Enhanced Chemical Vapor Deposition (PECVD), The optical and electrical properties of the samples were studied with ultraviolet-visible absorption spectrophotometer and Raman spectrometer. The results indicate that their transmittance decreased with the increase of the film thickness.
