Abstract
The integration of zinc oxide (ZnO) and cadmium sulfide (CdS) has shown promise in applications such as sensing and photovoltaics. We describe here a room temperature, aqueous synthetic strategy to selectively grow nanocrystalline CdS on ZnO. In particular, we describe an experimentally simple process that selectively grows a conformal nanocrystalline coating only 1 nanocrystal (10−20 nm) thick on planar and three-dimensional extended ZnO structures. We explore the synthesis, characterization, and mechanisms involved in the formation of this composite material, and we demonstrate a promising optical response from these composite structures that may prove valuable for future optoelectronic applications.
