Research Focus

In the Rosenthal group we study semiconductor nanocrystals, a novel material whose optical properties and electronic structure can be precisely tuned by controlling the size or composition of the nanocrystal. We perform fundamental optical studies for example: femtosecond florescence upconversion spectroscopy and single nanocrystal spectroscopy.  We are exploiting the properties of nanocrystals for implementation as biological probes for membrane proteins involved in neuronal signaling. We also have a program to explore the possible use of nanocrystal white light emitters for implementation in energy efficient solid state lighting and novel technologies.
