CdS nanorods with ZnSe seeds are developed. Rod growth is achieved for a seed with a zinc blende structure. Due to the type-I potential profile in this anisotropic nanoheterostructure, charge-carrier separation occurs in the excited state of the nanorod. Structural characterization is shown as well as static and time-resolved optical spectroscopy. A fluorescence quantum yield of 45% is achieved, demonstrating the exceptional optical properties of these structures.
