摘要：

Radiochemical synthesis of metallic nanoparticles is an eco-friendly method allowing the obtaining of controlled size, well dispersed and highly stable particles at very mild conditions. Colloidal silver nanoparticles were synthesized in a one-step process, in an aqueous system consisting of polyvinyl alcohol (PVA)/Ag+/isopropyl alcohol (IPA), irradiated at various doses by using high energy ionizing radiations (gamma-rays). The UV-Vis spectra have shown a maximum absorption peak in the range of 390 450 nm, specific for silver nanoparticles. The size of the obtained spherical shape nanoparticles was below 50 nm and decreased with increasing of the irradiation dose.
