Synthesis, characterization and photoluminescence of cdS hyperbranched nanocrystals by a simple solution chemistry method.

We report the synthesis of CdS hyperbranched nanocrystals using a simple hot coordination solvents method. Transmission electron microscopy studies showed that the length of the arms and the angle of branching could be controlled by varying organic surfactants in terms of amount and type. It was found that long chain carboxylic acids favored the synthesis of CdS hyperbranched nanocrystals.
