Abstract
Anisotropic gold particles were prepared in a gemini cationic surfactant so lution by reduction of HAuCl4 with UV irradiation. With increasing concentr ations of both HAuCl4 and the surfactant, fibrous gold particles were obtai ned and their length increased. These results suggest that the gemini surfa ctant which provides threadlike micelles operates as a soft template for an isotropic gold particles. (C) 1998 Academic Press.
