Carbon Dots Plasmonics Coupling Enables Energy Transfer and Provides Unique Chemical Signatures Academic Article uri icon

abstract

  • Plasmonic nanostructures and carbon dots (C-dots) are fascinating optical materials, utilized in imaging, sensing, and color generation. Interaction between plasmonic materials and C- dots may lead to new hybrid materials with controllable optical properties. Herein, we demonstrate for the first time coupling between plasmonic modes and C-dots deposited upon a plasmonic silver hole array. The coupling leads to a remarkable visual attenuation and shifts of the plasmonic wavelengths (ie color tuning). In particular, the C-dots …
