Preparation of colloidal Gold Nano particles Using Electro Chemical Method

Abstract

In this paper a process of electro-chemical system used for preparing colloidal Nano Gold particles in electrolyte medium. Thin films of gold nano particles and suspension gold prepared and examined by x-ray diffraction method. furthermore; Uv-vis spectra spectrophotometer was used to determined optical properties . Results show the electrochemical method is simple method to syntheses of colloidal Nano Gold particles with average particles less than of 50 nm. The fabrication parameters such as I(mA) , V(v) and T(C)) were examined . Red to grey color changed of gold suspension that related to preparation parameters and particle size was studied.
