Exciton-plasmon coupling interactions: from principle to applications
En Cao,En Cao,Weihua Lin,Weihua Lin,Mengtao Sun,Mengtao Sun,Mengtao Sun,Wenjie Liang,Yuzhi Song +8 more
TL;DR: In this article, the authors introduce the exciton-plasmon interaction from basic principle to applications, which demonstrate different optical properties, such as surface-enhanced Raman scattering, surface plasmon (SP)-enhanced absorption, enhanced fluorescence, or fluorescence quenching.
Journal ArticleDOI
Electrically enhanced hot hole driven oxidation catalysis at the interface of a plasmon-exciton hybrid.
TL;DR: This work fabricated an electro-optical device based on a graphene-Ag nanoparticle hybrid as the substrate of graphene mediated surface enhanced Raman scattering (G-SERS) manipulated by the gate and bias voltages, revealing that the hot holes on graphene mainly contribute to plasmon-exciton co-driven oxidation reactions.
