Outline of Final Research Achievements

We employed radio frequency plasmas in water to produce metal-nano-materials. We mainly produced gold nano-particles. There are two systems to generate RF plasmas: One is the system where the plasmas are on a hot electrode. In the other system, they are generated in a hole of an insulating plate between the electrodes. The method of nano-materials is reduction of metal ions or spattering of metal electrode. In all cases, the products depend on concentration and kind of salt. The control of salt can produced gold nano-wires and gold nano-pentagons. When plasmas are generation in a hole of an insulating plate, there are no contaminations from the metal electrodes, where bubble formations are important to generate plasmas.
