碩士 === 國立中正大學 === 化學所 === 93 === The synthesis and application of nanoparticles were importance in nanotechnology. We tried to use different nanomaterials to make up anisotropic nanostructures by chemical methods. To achieve the synthetic work of gold-silver nanocomposite particles, we were designed three steps. The first, we were synthesized gold nanorods by electrochemical method and the second were proceed asymmetric cover in the surface of gold nanorods. The third, we were developed silver nanoparticles in the exposed ends of gold nanorods. The synthesis of anisotropic nanoparticles and the size of silver nanoparticles which were controlled with several parameters, including changed the concentration of the precursor solution (HQ silver) and asymmetric cover in the surface of gold nanorods. We were also conferred the mechanism that formation of anisotropic nanostructures.
