Hybrid semiconductor nanocrystals (NCs) consisting of separate donor-acceptor domains are viewed as promising candidates for increasing the efficiency in present-day photovoltaic and photocatalytic applications. Properties of colloidal heterostructured nanocrystals are largely determined by the spatial distribution of photogenerated carriers across the junction of semiconductor materials that form the heterostructure. The two known types of carrier distributions are identified based on whether both carriers reside within the same (type I) or opposite (type II) sides of the heterojunction. Herein, we report on organometallic synthesis of semiconductor heterostructured nanocrystals (nanorods, core/shell nanocrystals, Alloy nanocrystals and nanobarbells) that produce a number of unique properties including enhanced magnitude of quantum confined Stark effect, efficient spatial separation of carriers in between acceptor and donor, and subnanosecond switching of absorption energies that can find practical applications in electroabsorption switches, solar cell and ultrasensitive charge detectors.
