This dissertation describes the fundamental studies of photoinduced charge-carrier transfer from colloidal metal chalcogenide quantum dots (QDs) to surface-adsorbed molecular redox partners. In addition, we also present the use of visible-light absorbing QDs in photocatalytic applications. CdS QDs are used as photocatalysts in a C-C coupling reaction, in which no...
Semiconductor nanocrystals possess unique photophysical properties that make them desirable for many optoelectronic applications such as photovoltaics, LEDs, and quantum computing. When the size of a semiconductor is reduced to below the excitonic Bohr radius of the material, its carriers becomes quantum confined resulting in drastic changes to optical, electronic,...
