摘要：

The review of results on nanoparticles formation is presented under laser ablation of Ti, Ag, Au, CdS, and ZnSe solids targets in liquid environments (H2O, C2H5OH, C2H4Cl2, etc.). The use of a high-repetition-rate Cu vapor laser (wavelength of 510.5 nm, 20 ns pulse duration, repetition rate of 15 kHz) allows high rate of nanoparticles formation as the suspension in the liquid. X-ray diffractometry (XRD), UV-Vis optical transmission spectrometry, and High Resolution Transmission Electron Microscopy (HRTEM) characterize the nanoparticles. The size of nanoparticles is studied as the function of both laser fluence and nature of the liquid. A theoretical model is derived for evolution of the distribution function of particles size under laser ablation. The influence of laser parameters as well as the nature on the liquid on the properties of nanoparticles is elucidated.
