报告摘要:
In
this talk Dangyuan Lei will introduce a fast emerging research area of
nanophotonics – plasmonics, which studies the nanoscale light-matter
interaction and applies the enhanced electromagnetic response of metallic
nanostructure resonators in a wide range of applications such as
optoelectronics, biosensing, bioimaging, energy and environment. Of particular
interest here is the recently developed nonlinear plasmonics research that uses
the spatially confined, intensity-amplified local electromagnetic fields of
metallic nanostructures to boost up the nonlinear conversion efficiency of
metals, including optical harmonic generation (SHG) and two-photon
photoluminescence (TPPL), and the emission efficiency of nonlinear optical
materials nearby plasmonic resonators. Following a brief overview of the
ongoing research activities and facilities available in their group, he will
present their recent research results on 1) plasmonic meta-molecules with
pronounced Fano resonances for ultrasensitive molecular sensing and enhanced
second-harmonic generation, 2) plasmonic golden junctions for enhanced
SHG/TPPL/hyper-Raman scattering, and 3) plasmon-enhanced nonlinear emissions
from upconversion nanocrystals for improved bioimaging.
报告人简介:
Dangyuan
Lei received his BSc and MPhil degrees, both in Physics, from Northwest
University and The Chinese University of Hong Kong in 2005 and 2007,
respectively. In October 2008, he went to Imperial College London to conduct
his PhD study, under supervision by Prof. Stefan Maier and in long-term
collaboration with Prof. Sir John Pendry, and obtained his PhD degree in
Physics in 2011. He is currently an assistant professor in the Department of
Applied Physics at The Hong Kong Polytechnic University since September 2012.
His main research activities include nanophotonics and nanomaterials studies,
with particular interest in surface plasmon-enhanced light-matter interaction
at the nanoscale and their applications in energy harvesting, optoelectronic devices,
biochemical sensing and biomedical imaging. Since 2007, he has published 74
peer-review journal publications including 22 publications in Nature
Communications, Light: Science & Applications, Nano Today, Advanced
Materials, Nano Letters, ACS Nano, Physical Review Letter, Energy &
Environmental Science, Nano Energy, and Chemistry of Materials, with a total
citation of 1780 times (by Google Scholar as of November 2016). He has received
several prestigious awards, including the “Deputy Rector’s Award” (2008-2011)
and the “Anne Thorne PhD Thesis Prize” both from Imperial College London, the
“Early Career Grants Award” from the Hong Kong Research Grants Council (2013),
the Journal of Materials Chemistry C Emerging Investigator from the Royal
Society of Chemistry (2016), and a Royal Society International Exchange award
(2016).
