چکیده:

Colloidal silver nanoparticles are prepared by gamma radiation reduction of silver ions using polyvinyl pyrrolidone as a stabilizer. The products are characterized by UV-vis spectrophotometry and scanning electron microscopy (SEM). The higher dose of γ-irradiation provided silver nanoparticles with higher concentration as evidenced from UV-vis absorption spectra
