Nano-sized particles have unique properties compared with bulk

materials due to quantum size effects and surface effects.1−4

Preparation of nanoparticles with the well-defined morphology,

structure, and chemical composition is crucial for achieving their

unique properties that make them attractive for various practical

applications, including microelectronics, medicine, heterogeneous

catalysis, nonlinear optics, and so forth.5,6 Depending on the size

range, shape, and chemical composition of nanoparticles, different

techniques are used for producing such samples. Among them

are wet chemical processes, physical methods, and combined

techniques. Recently, pulsed laser ablation (PLA) of solid samples

submerged in liquid has been shown to have a great potential for

fabrication of nanoparticles.7−11 Compared with PLA in a vacuum or gas environment, PLA in a liquid medium has the advantage of

preparing nanoparticles without using large-scale vacuum appara-

tus (laser ablation is performed in liquid at atmospheric pressure),

maintaining the stoichiometric ratio of the chemical components in

the resulting product, and providing the capability of the synthesis

of nanoparticles of different compounds, as a function of nature

of the solution and the sample material. Unlike the arc discharge

method, which requires electrically conducting electrodes, PLA in

liquids can be applied universally for an almost unlimited variety of

materials, including metals, semiconductors, and insulators as well

as different kinds of liquids.
