| Outline of Final Research Achievements |
Nanoparticles of silver and gold have been produced in THF and PGMEA in one step by using the gamma-irradiation of Ag＋ and KAuCl4 solutions, and stabilization with the polymer PMMA.The radiolytic yields of silver or gold nanoparticles are somewhat lower than in water or alcohols, because of the very low dielectric constant and the stronger competition of the metal ion reduction with the geminate recombination between the solvated electron and the parent cation.These results showed it is possible to construst metal nano-structure by using the combination of top-down and bottom-up nanofabrication.
