Laser Synthesis of Gold Nanostructures at Atmospheric Pressure: Nature and Applications

Abstract

Consideration has been given to certain aspects of condensation processes occurring in laser-induced erosion plumes of gold and giving rise to fluxes of golden nanoparticle at atmospheric pressure. Samples of colloidal solutions of gold and gold-containing polymer films have been produced as a result of penetration of nanoobjects formed in erosion plume of gold into aqueous and polymer-containing media. On the base of air laser synthesis it can be also possible to obtain the gold surface island-shaped nanostructures in the form of nanocones widely distributed with height. Experimental samples formed have been comprehensively investigated using optical spectroscopy, atomic-force microscopy, transmission and scanning electron microscopy
