Place:  Room 104，Building 1，State Key Laboratory for silicon materials，Yuquan Campus

Inviter:  Prof. Dongsheng Li

Abstract:

Nanoplasmonics studies the nanoscale light-matter interaction and applies the enhanced electromagnetic response of metallic nanostructure resonators in a wide range of applications such as nanoscale optoelectronics and energy harvesting. Of our particular interest here is the recently emerged nonlinear and chiral plasmonics research because it provides tremendous opportunities for advancing the biophotonics research and for developing novel biochemical imaging and sensing platforms. In this talk, I will discuss how the nonlinear plasmonics concepts and nanostructures can be used for the development highly efficient near-infrared multiphoton bioimaging probes and their extension to super-resolution optical microscopy. I will also discuss briefly future prospects of nanoplasmonics and nanophotonics in biochemical sensing, super-resolution imaging and light-triggered energy conversion.

Bio:

Dangyuan Lei received his BSc, MPhil and PhD degrees all in Physics from Northwest University, The Chinese University of Hong Kong and Imperial College London in 2005, 2007 and 2011, respectively. He has been an assistant professor with 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 plasmon-enhanced light-matter interaction at the nanoscale and their applications in energy harvesting, optoelectronic devices, and biophotonics. Since 2007, he has published 95 journal publications, including 30 articles in Nature Communications, Light: Science & Applications, Physical Review Letters, Advanced Materials, Nano Letters and ACS Nano etc., receiving 2810 citations and an H-index of 31 (by Google Scholar as of May 2018). Two publications have been respectively selected in the RSC “Emerging Investigators” themed issue of Journal of Materials Chemistry C (2016) and the IOP “Emerging Leaders” edition of Journal of Optics (2017). He has received several prestigious awards, including the “Deputy Rector’s Award” (2008-2011) and the “Anne Thorne PhD Thesis Prize” (2012) both from Imperial College London, the “Early Career Grants Award” from Hong Kong Research Grants Council (2013), a Royal Society International Exchange award (2016), and a Key Technology Partner Visiting Fellow of University of Technology Sydney (2017).
