Control of Formation Efficiency and Stability of Nanoparticles in Laser Ablation in Liquid

Abstract

The promising technique of laser ablation in liquid (LAL) is attracting much attention to produce nanoparticles of various materials using a simple experimental procedure. Because of the differences in the formation process of nanoparticles in LAL from those in laser ablation in gas, the important factors, which influence the formation efficiency of nanoparticles, are different between LAL and LAG. In this review, we introduce factors and methods to improve formation efficiency. The stability of colloidal nanoparticles is also an important aspect of LAL as a colloid synthesis technique. Although one of the most remarkable features of LAL is that pure colloids are obtained, the stability and the usability of colloids are greatly improved by stabilizing reagents.
