The article is concerned with the study of the structure of silver nanoparticles formed in a hydrogel as a result of irradiation of a solution of silver nitrate in a mixture of polyvinyl alcohol and polyethylene glycol by high-energy electrons. The reduction of Ag nitrate to metallic silver as a result of irradiation is confirmed by x-ray diffraction analysis. The dynamic light-scattering method confirms that, in irradiated liquid solutions of AgNO3, the nanoparticles’ size distribution is bimodal. The presence of predominantly spherical silver nanoparticles and Ag2O ones is revealed by transmission electron-microscopy method.

Key words: silver nanoparticles, hydrogel, high-energy electron irradiation.
