| Outline of Final Research Achievements |
Effect of protective agents on the preparation of silver nanoparticles by vacuum evaporation on running oil substrate method was investigated. Among five kinds of protective agents bearing a common hydrophobic group (oleyl group), silver nanoparticles, which can be finely re-dispersed in the solvent, were obtained in the high yield in the case of oleic acid. In addition, near-infrared fluorescent silver selenide nanoparticles, which can finely disperse in water, could be obtained by atom transfer radical polymerization of hydrophilic monomers (oligoethyleneglycol methacrylate).
