Colloidal Semiconductor Nanocrystals
This GRC will focus on the chemistry and physics of colloidal semiconductor nanocrystals (quantum dots and anisotropic structures). These materials are discrete crystals of semiconductor materials with diameters on the length scale of exciton coherence in the bulk semiconductor, which results in distinctive optoelectronic properties. The conference will specifically focus on colloidal (as opposed to epitaxial) nanocrystals. These nanocrystals are chemically synthesized in organic media and their surfaces are passivated with approximately a monolayer of organic surfactant that solubilizes the nanocrystals in solvent dispersion, but also performs a range of potential functions, including electronic passivation of surface states, mediation of chemical interactions with other materials, and redox chemistry with the nanocrystals core. The photophysical behavior of the nanocrystal - that is, the evolution of its photoexcited states - is intimately related to this surface chemistry, and to the chemical properties of the nanocrystal’s core.
The goals of this GRC are to explore the photophysics of colloidal nanocrystals in terms of the properties of both the core and the surface, and to highlight (i) synthetic methods to tune the surface chemistry of nanocrystals, (ii) new approaches, techniques, and analytical methods that quantitatively characterize the core and surface chemistry of these nanocrystals, and (iii) photophysical studies (both time-resolved and steady state) of quantum dots that relate excitonic decay pathways to chemical properties of the nanocrystals, (iv) spectroscopies that directly probe the coupling of electronic excitations to phonons of the core lattice and vibrations of the surface ions and ligands, and (v) methods to form and properties of assemblies of nanocrystals.
What is a GRC? Gordon Research Conferences (GRC) are 5-day meetings that bring scientists together from around the world to present and discuss unpublished research with other leaders in their field.
This Gordon Research Conference (GRC) series is related to the "Colloidal Semiconductor Nanocrystals" Gordon Research Seminar (GRS)
series. Although a related GRS will typically be scheduled in conjunction with its parent GRC each time it meets, that may not always be the case. Refer to the individual meetings in the Meeting History
section below for more details. For more information about the associated Gordon Research Seminar (GRS) series, click here
.What is a GRS? Gordon Research Seminars (GRS) are 2-day meetings that bring graduate students and post-docs together to discuss their cutting edge research among peers and mentors. Each GRS immediately precedes an associated Gordon Research Conference (GRC), and topics addressed at the GRS relate closely to the GRC.
