The field of colloidal nanoparticle research has exploded over the past 15 years, after foundational work in the 80s and 90s. Much progress in the field arose from simple synthetic skills and rather standard optical spectroscopy and electron microscopy imaging.  While C60 and carbon nanotubes were the first “nanochemicals” to generate public enthusiasm in nanotechnology, mostly through savvy public relations and commercial gimmicks, (remember tennis rackets with carbon nanotubes?), colloidal nanoparticles have had a greater stream of potential applications such as biological probes, light emitting displays, phosphors, and photopholtaic panels. Transfer to actual products has been slower than expected because of lackluster performances in some parameter space, but there are still many undiscovered materials and properties.  In this lecture, after a broad introduction of this exciting field at the interface of chemistry and physics, Professor Philippe Guyot-Sionnest described two promising research directions in his laboratory, on magnetic colloidal quantum dots and infrared photodetection.

Philippe Guyot-Sionnest holds joint appointments as Professor in the Departments of Chemistry and Physics at the University of Chicago.  He earned his PhD from the University of California, Berkeley, in 1987 after attending the Ecole Polytechnique, Palaiseau, France and the University of Paris-Sud, France.  Guyot-Sionnest's awards include: 2002 Fellow, American Physical Society; 1992 David and Lucile Packard Fellow; and 1990 Prix National des Lasers, Sociètè Française de Physique.  His research focuses on the synthesis of colloidal plasmonic nanostructures with specific optical properties.
