Outline of Final Research Achievements

In this study, I focused on an environmental friendly synthesis method of metal nanoparticles by using metal containing glass, by which particle size of nanoparticles can be well controlled, and investigated its generation mechanism of nanoparticles and an effect of glass composition. In a silver-containing glass system, silver ions, which are precursors of silver nanoparticles, did not be dispersed in reaction solution. It was suggested that silver nanoparticles were generated in or near surfaces of the glass. Also, it was suggested that solubility of silver-containing glass to water effect on a rate of nucleus growth of silver nanoparticles, rather than that of nucleus generation.
