Understanding secondary light emissions by plasmonic nanostructures
Urbana IL (SPX) Jan 17, 2014
"Plasmonic nanostructures are of great current interest as chemical sensors, in vivo imaging agents, and for photothermal therapeutics," explained David G. Cahill, a Willett Professor and head of the Department of Materials Science and Engineering at Illinois. "Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or 'secondary light emission'. The interpretation of resonant secondary light emission in terms of fundamental proces ... read more
