Abstract: 

A one-pot synthesis method has been developed for preparation of silver nanoparticles in aqueous poly (vinyl pyrrolidone) (PVP) solution by synchrotron X-ray radiation. The hydrated electrons (eaqˉ) and hydrogen atom radical (H·), products of radiolysis of water molecules by synchrotron X-rays brings about the reduction of the metal ions, resulting in homogeneous nucleation and nanoparticle formation. The nanoparticles were characterized by UV-visible spectroscopy and TEM analysis. A comparative study has been done to know the effectiveness of this synthesis method with that of gamma and EB- irradiation methods. In gamma radiation method the nanoparticle size obtained was ~8nm, whereas in synchrotron X-ray irradiation 10-15nm particles were obtained. Smaller size particles with narrow size distribution were obtained by g-radiolysis and EB-irradiation than those obtained by X-ray radiolysis. The effects of different experimental parameters, such as concentration of Ag+, PVP concentration on nanoparticle formation were studied. Copyright © 2013 VBRI press.
