The shape and morphology controlled synthesis of semiconductor nanostructures has provided new possibilities to improve their physical and chemical properties. In this study, a series of CdS flower-like nanostructures have been synthesized through facile hydrothermal decomposition of the as-formed cadmium diethyldithiocarbamate (Cd-DDTC) single-source precursor in its precursor solution. The morphologies of the nanostructures can be controlled by manipulating the precursor concentration and the reaction time. XRD studies reveal that CdS multipod nanostructures have [001] preferential crystal growth direction. A possible growth mechanism is proposed to explain the morphology control of CdS nanostructures resulting from a balance between the thermodynamic and kinetic growth regimes. The CdS multipod nanostructure has photoluminescence emissions at 528 nm and 615 nm. The size and morphology dependent UV-vis absorption properties were investigated.
