TEM images representing the morphology and dispersion of colloidal AgNPs. Top panel are images of AgNPs prepared in 2% (w/v) PVA solutions at irradiation doses of (a) 20, (b) 40, and (c) 60 kGy. Insets show histograms of size distribution. In lower panels, AgNPs were formed at the irradiation dose of 60 kGy in (d) 5% (w/v) SF, (e) 0.5% (w/v) PVA, and (f) 1.0% (w/v) PVA solutions.
