报告摘要:
Colloidal plasmonic nanocrystals exhibit very attractive optical properties. They have proven to be of enormous potential in a wide range of applications. To fully realize their technological potential and further explore their fundamental plasmonic properties relies on the ready availability of high-quality, high-performance nanocrystal products at different amount scales. We have made tremendous efforts over the past decade on the development of synthetic methods for colloidal metal nanocrystals. We have been able to synthesize several types of highly uniform colloidal Au and Ag nanocrystals, investigated their plasmonic properties, and explored a variety of plasmon-enabled applications. In this presentation, I will first describe how we make colloidal plasmonic nanocrystals. I will then talk about plasmonic photocatalysis based on hot electrons and hot holes, and active plasmon switching. Finally I will mention two most recent developments in our group, namely, magnetic plasmon resonance and high-refractive-index dielectric nanostructures, in the field of nanoplasmonics.
