Abstract: In this paper we report the effect of irradiation time on the morphological and dimensional properties of colloidal silver nanoparticles (AgNPs) using sodium citrate and silver nitrate as reductant and oxidant, respectively under microwave irradiation. The prepared NPs were characterized by UV–vis spectroscopy, Particle size analyzer (PSA), transmission electron microscopy (TEM) and selected areas electron diffraction (SAED). The formation of Ag NPs was confirmed by the appearance of a surface plasmon absorption between 411-425 nm. PSA showed that the colloidal nanoparticles had a diameters ranging from 25.5-41.2 nm. TEM images showed that the diameter of the silver nanoparticles in accordance with the results obtained using PSA. The rings patterns are in good agreement with the standard values of the facecentered-cubic form of silver nanocrystals.
