세미나 제목 : Plasmonic gold nanoparticles for nano- and bio-photonic applications

발표초록 :

Plasmonic gold nanoparticles have been at the centre of attention in nanoscience and technology due to their extraordinary optical and physical properties. Recent advances in its application to high density optical storage and cancer therapeutic agents [1-4] utilize its strong linear and non-linear absorption, near-field enhancement and plasmon-coupling in 1- 20 nm regime. While many applications are being demonstrated, fundamental understanding of these advances is still lacking. Where does the metal luminescence come from? How does the shape play a role in the luminescence? What are the material limitations? Is the stability of particle shape critical in success of these applications? How does the reshaping of these particles occur? In this talk, I will present recent spectroscopic studies of single gold nanoparticles (luminescence, scattering and correlation spectroscopy) at Optical Nanomaterial Spectroscopy group in addressing these important questions for future success of their application.
