Controlling the structure of matter at the nanoscale opens exciting opportunities to manipulate the properties of materials with great flexibility and precision. Nanoparticles that support plasmon resonances can effectively confine light into nanoscale volumes, whereas nanoparticles that exhibit quantum confinement show unique size- and shape-dependent properties. Either used independently or together, these plasmonic and quantum-confined nanoparticles have important implications for tailoring electromagnetic radiation in solar energy conversion, light-emitting devices, sensors, therapeutics, information technology, and numerous other applications. Recent studies have significantly advanced our fundamental knowledge of the electronic structure, carrier dynamics, and interactions between incident electromagnetic radiation and these nanoscale materials. In parallel, progress in synthesis and fabrication of nanostructures has also enabled unprecedented control over the size and shape of the nanostructures. Many of these academic advances are now being adopted by industry and used in innovative commercial applications. This symposium will bring together scientists and engineers working on quantum-confined nanocrystals and plasmonic nanostructures to discuss the most recent progress in their design and characterization, as well as showcase the transition of these materials to applications.
