Research Highlights and Focus Area

Overall, we develop new synthetic approaches to novel functional optical nanomaterials. We explore nanoscale heterostructuring as a means to enhance fundamental photophysical properties or to completely evolve new, emergent or multifunctional behaviors. We aim to establish design principles that guide our synthetic and materials choices toward optimized and novel properties. We actively pursue innovative synthetic methods that build upon traditional colloidal and inorganic materials chemistry but incorporate automation, in situ characterizations, and microfluidics platforms. In addition to directly “constructing” nanoscale interfaces into nanocrystals through synthesis toward enhanced or new properties (e.g., “thick” semiconductor shells to eliminate blinking, electronic structure manipulation for functional bandgap engineering, plasmonic-semiconductor interactions, or magnetic-semiconductor multifunctionality), we utilize and advance approaches for post-synthesis assembly of nanocrystals to realize mesoscale interfacial interactions and collective behavior (e.g., dip-pen nanolithography, bio/polymer-templating). We collaborate extensively with spectroscopists and theorists to fully understand correlations between composition, structure and function that further inform our materials development efforts. We also apply our novel nanomaterials and provide proof-of-principle demonstrations of their unique utility for applications from biology to energy.
