Center for Functional Nanomaterials Colloquium Series Quantum dot based hybrids for light harvesting, plasmonics and biosensing Mircea Cotlet Center for Functional Nanomaterials, Brookhaven National Laboratory, Upton, NY Tuesday, February 18, 2014 11:00 am Bldg. 735 â€" Seminar Room, 2nd Floor Colloidal quantum dot (QD) based hybrids have been intensively utilized in hybrid photovoltaics, light emitting diode and biosensing applications. The combination of such inorganic nanomaterials with organic and biological moieties can produce functional nanomaterials with novel properties. The resulting properties of such hybrids highly depend on the interaction between components and this needs to be controlled/tailored towards a particularly proposed application. In my talk I will present several examples of such QD-based nanomaterials where through the use of self-assembly and nanocrystal synthesis we were able to demonstrate control/tunability of optoelectronic properties like charge and energy transfer. I will also discuss the implication of such processes on the photoluminescence properties of quantum dots as we have learned from single particle optical investigations.
