Abstract
Highly-ordered periodic structures of the gold nanoparticles (AuNPs) are formed by transcribing the plasma structure to the surface of the liquid, where the spatially selective synthesis of the AuNPs is realized. Furthermore, the plasma structure is controlled by using a ring or disk electrode under the strong magnetic fields up to 4 tesla. The ring structure of the nanoparticles is found to be formed in accordance with the shadow region of the ring electrode. It is found that the AuNPs are synthesize by the reduction effect of the hydrogen radical via irradiation of neutral radical of the plasma and are destroyed by the oxidation effect of the fluorine radical via high-energy plasma ion irradiation.
