| 초록 |
Shape and size controlled synthesis of gold particles has been studied by using wet-chemical method. When AuCl4 - in aqueous HAuCl4 precursor was reduced using Na2SO3 as a reducing agent, mixtures of spherical, triangular and hexagonal particles were prepared in a few minutes. It was found that the shape selective oxidative etching by AuCl4 - + C l-
anions and crystal growth took place simultaneously. As the AuCl4 - and Cl- concentration increased, yields of large triangular and hexagonal plate type particles increased, while the spherical particles decreased in most cases. Possible etching and growth mechanisms are discussed. |
