Surface Plasmon Resonance Extension of Au-PPy Two-block Nanorod Structures |
| 초록 |
Surface plasmon resonance coupling of metallic nanostructures is one of the important aspects in plasmonic since distinctive collective optical properties can be realized, different from the individual constituents. Plasmonic coupling of metal-metal nanostructure systems have well been explored for a long time, yet plasmonic characteristics of metal-organic nanostructures is still challenging. Most studies are limited to the investigation regarding electrical properties or conducting matrices for assemblies with metallic nanoparticles. Here, we report localized surface plasmon resonance of colloidal-dispersed Au-PPy nanorods synthesized by modified electrochemical method and collective oscillation properties were systematically investigated by comparing with pure Au nanorods. Importantly, we investigated the extended surface plasmon resonance of hybrid system for the first time. The presence of doped-PPy segments on Au segments induces the enhanced electric field coherently due to the partial contribution of π-electrons on PPy segment, which leads to the red-shifted plasmon feature. Additionally, we demonstrated that surface plasmon resonance extension can be tuned by dopant anions, which paves the way for dopant-induced plasmonic tuning system. |
