Abstract

Colloidal semiconductor nanocrystals are a promising class of functional materials that have been the subject of intense research and development for over thirty years due to their highly tunable optical and electronic properties. Potential applications that can take advantage of these tunable parameters include nanoscale photonics, light-emitting diodes, biological labeling/imaging, and next-generation solar energy capture, conversion, and storage strategies. Nanoscale physicochemical structure drastically influences nanocrystal optical and electronic behavior; therefore, a more thorough understanding of how to manipulate, characterize, and optimize nanoscale composition, size, and shape is necessary for their wide-spread technological implementation. This thesis explores how postsynthetic modification of colloidal semiconductor nanocrystal physicochemical structure affects emergent optical and electronic properties.
