Abstract Details: Semiconductor nanocrystals (NCs), also known as colloidal quantum dots, are well-known for their exhibition of strong quantum confinement effects and have been utilized in applications as diverse as biomedical diagnostics, optical gain media, LED’s and photovoltaics. Several of these applications have been commercialized into products such as fluorescent probes from InvitrogenTM and display technologies from Sony Corporation. While the synthesis of semiconductor NCs was introduced about two decades ago, innovations in the synthetic preparation of these nanoparticles remains to the present day a very active area of research. In this talk, I will describe how recent developments in the synthesis of NCs have produced hierarchically complex structures with dimensions ranging from 1D to 2D (from rods to sheets). I will draw from examples of nanoparticles synthesized in my research group and will elaborate on how some of these structurally complex nanoparticles incorporate multiple functionalities within the same nanostructure or produce physicochemical properties not achievable by conventional quantum dots.Click HERE for directions
