| Outline of Final Research Achievements |
We have studied a new method for preparation of metal nanoparticles such as gold, silver, and copper by “light”. We successfully developed a new method consisting of photoirradiation of water containing metal precursors and photoresponsive reducing agent. In that, the added reducing agent behaves as a surface stabilizing agent that suppresses aggregation of the formed metal nanoparticles. The proposed method facilitates the formation of metal nanoparticles with tunable sizes and narrow size distributions.
