报告摘要

The “plasmon hybridization”concept,[1] shows that the plasmon resonances in complex metallic nanostructures interact and hybridize in an analogous manner as atomic wavefunctions in molecules. The insight gained from this concept provides an important conceptual foundation for the development of new plasmonic structures that can serve as substrates for surface enhanced spectroscopies, chemical and biosensing, and subwavelength plasmonic waveguiding and other applications. The talk is comprised of general overview material interspersed with a few more specialized “hot topics” such as plasmonic Fano resonances,[2] quantum plasmonics,[3] quantum plexcitonics,[4] and active plasmonic nanoantennas for enhanced light harvesting,[5] plasmon induced chemical reactions,[6] and nanoparticle enabled solar driven steam generation.[7]
