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.

Oxidation characteristics of colloidal silver nanoparticles produced by pulsed laser ablation in pure and chemically treated water are studied as a function of the degree of ozonization. The bright yellow colloidal solution of silver characterized by a sharp surface plasmon mode at ~400 nm, becomes colorless in the initial stages of O 3 flow, and then acquires a brown hue with a broad plasmon peak centered at ~440 to ~450 nm on further ozonization. The solution again becomes colorless in a few days once the O 3 flow is stopped. We present a qualitative model for the reaction dynamics and analyze the optical absorption in the framework of an effective medium theory. The aqueous phase laser ablation chemistry described here provides a unique means to produce ionic silver for enhanced antimicrobial effects.
