Fabrication of nanostructures by plasma and laser assisted synthesis in liquids

In this paper capabilities of electrical discharge plasma and laser irradiation processes in liquids for synthesis of nanoparticles (NPs) of different morphology and composition are discussed. The main attention has been focused on the properties of carbon, silicon, as well as alloyed and composite NPs. Particles with size in the nanometric range (3-50 nm) with different crystal structures were produced depending on the preparation procedure. In addition, the targeted changes of the NPs properties (their size and composition) were shown to be sensitively controlled via additional plasma and laser treatment of the prepared suspensions. It is supposed that under additional laser irradiation the compound nanoparticles are formed in result of nanoparticles heating, co-melting and chemical reactions in the liquid droplet.
