Research Abstract

Radiation-induced synthesis of composite nanoparticles consisting of noble metals and ceramics in an aqueous solution system has been investigated. In this work, radiation-induced formation processes of noble metal composite nanoparticles in aqueous solutions were observed by UV-vis absorption spectroscopy. The influence of temperature and other factors on growth curves of surface plasmon peak of noble metal nanoparticles was observed. The relation between kinetics of formation process and condition in aqueous solution was discussed.
