Abstract EN
In this work, Silver nanoparticles prepared by arc discharge method in deionized water by applying stablized direct current between two silver rods which are submerged in deionized water at room temperature without any heat exchanger, vacuum equipment and gas handling equipment.
During electrical discharge the temperature between electrodes can reach several thousand Celsius degrees.
This leads to etch of silver electrodes in deionized water, silver vapor condensed in water creats a stable silver aqueous suspension.
The silver nanoparticles were characterized by UV-Visible photometer, X-Ray Diffraction (XRD), and Atomic Force Microscope AFM.
The optical absorption measurement shows that the spectrum exhibits a Plasmon absorption band at ~ 400 nm which is the characteristic of silver nanoparticles.
X-Ray Diffraction of the resulting NPs indicated that the particles had a crystalline structure and the average particle size determined from AFM, is about 78.75 nm.
