Synthesis and Characterization of Gold Nanorods by a Seeding Growth Method
Abstract:This paper focuses on the synthesis of gold nanorods by a seeding growth approach in the presence of cetylthrimethylammonium bromide as a weak reducing agent. The pH value of the solution is an important factor in the formation and control the morphology of gold nanorods. In the pH-dependent range from pH 3.3 to pH 2.2, the main product that gold nanorods with the aspect ratio of 18.7 were produced. The effect of the pH value of the aqueous solution on the aspect ratio of gold nanorod was discussed.
