Phase and shape controlled synthesis of CdS nanocrystals and their characterization.
We demonstrated simple solution based methods for preparing CdS nanostructure materials with distinct and well-defined morphologies, including spherical, rod and tripod/tetrapod by varying the solvents. It is also found that solvent plays an important role on tuning the crystal structure of nanocrystals, which is an important observation in this study. The mechanism related to crystal phase control is proposed and discussed. Our results reveal that the luminescence properties of CdS nanostructures depend on the size not on the shape of nanocrystals.
