The development of the automated installation to synthesize nanoparticles of noble metals by the method of laser ablation of volume targets in liquid

Abstract

The authors have developed the automated installation to obtain nanoparticles of noble metals by the method of laser ablation of volume targets in liquid. The installation contains the system of target displacement for its uniform irradiation and the original licensed flow system with control of nanoparticle concentration in solution by optical transmission and with feedback. The installation with fundamental harmonic pumped Nd: YAG pulse laser allows synthesizing continuously colloid solutions of Ag, Au and Pt nanoparticles in the range of concentrations 0,01…0,1 g/l with high frequency.
