Properties of gold nanoparticles produced by laser ablation volume targets in different environments

Abstract

In this work the Au nanoparticles are obtained by ablation of golden target in liquid solvents. It is found that depending on the environment of the gold nanoparticles have different diameters. The position of the maximum absorption of the plasmon of Au nanoparticles depends on the environment. It found that stable nanoparticles of Au that were prepared in acetone, isopropyl alcohol and ethylene glycol as the change of optical density values are insignificant. Shortwave maximum in the spectrum of the scattering particles are associated with the scattering of light by small particles, and the long-wave scattering - by large particles.
