Preparation of colloidal silver nanoparticles in poly(N-vinylpyrrolidone) by γ-irradiation
Source abstract
Abstract
Colloidal silver nanoparticles were prepared by γ-irradiating Ag+ in aqueous solution in the presence of 2% polyvinyl pyrrolidone (PVP) as stabilising agent and ethyl alcohol as free radical (OH•) scavenger. The saturated conversion dose of Ag+ into Ag was determined by UV–Vis spectroscopy and the silver nanoparticles size was characterised by transmission electron microscopy. The influence of Ag+ concentration (1–50 mM) on the saturated conversion dose and average diameter of silver nanoparticles was investigated. Results showed that the saturated conversion dose was from 8 to 48 kGy and the silver particles size was in the range of 6–21 nm for Ag+ concentration from 1 to 50 mM. The effect of PVP molecular weight on silver particles size was studied as well.
