Controlling crystal growth orientation and crystallinity of cadmium sulfide nanocrystals in aqueous phase by using cationic surfactant

Dispersed CdS single crystals were obtained via a hydrothermal method by using cetyltrimethylammonium bromide (CTAB) as a surfactant. The strong interaction between the cationic head group of CTAB and the (001) plane of CdS hexagonal crystals results in a single-crystalline growth along the [100] direction.
