光子技术研究院学术报告(72)

题目:Enhanced Light Radiation by Single PlasmonicNanoparticle

报告人:张天悦博士

主持人:李向平教授

时间:2016年6月15日下午3:30

地点:曾宪梓科学馆405会议室

 

报告摘要:

Noble metallic nanoparticles support localized surface plasmon resonances(LSPRs), collective oscillations of surface electrons that provide an avenue for thecontrol and manipulation of photons at the nanoscale, known as optical antennas.Optical antennas have been widely studied in this past decade for their ability tofocus incident light into tiny volumes. Reciprocally, the large amplification of thelocal electromagnetic density of states provoked by the antenna can increase the decayrates of nearby quantum emitters. In this report, I will present theplasmonic-enhanced light radiation based on the surface plasmons of an individualmetallic nanoparticle, including the photoluminescence involving radiative decay ofparticle plasmon itself and plasmonic-enhanced light-matter interactions through thecoupling radiative molecular emission to a radiative LSP mode.

I will also briefly introduce some optical manipulation techniques using optical trapping and printing and using AFM probe.
