Abstract:

Periodic gold nanowire arrays are prepared and several light nanoparticle molecule interaction phenomena related to such structures are discussed. A strong coupling between surface plasmons and molecular excitons are experimentally demonstrates, and their hybrid states using a quantum model by quantizing the collective plasmonic behavior are theoretically described. With respect to Surface enhanced Raman Scattering, an approach based on light induced molecular degradations to identify the enhancement contribution from chemical mechanisms are introduced. This work could improve the understanding of surface plasmon-molecule interaction phenomena in metallic nano structures and improve the design of surface plasmon-molecule interaction based sensors, devices and techniques.

Brief CV of Dr.Hongdan Yan: 

Hongdan Yan received a doctor degree in the institute of condensed matter physics, Technical University of Braunschweig in Germany in 2012. Now she is working as a researcher in the Laboratory of Emerging Nanometrology, TU Braunschweig. A main research direction is about light-nanoparticle –molecule interaction behavior based on surface plasmonics of gold nanoparticles.
