Title: Fabrication and modification of different nanoparticles by laser irradiation process.
Nanoparticles were the first and remain one of the most important subjects in Nanoscience and Nanotechnology. A variety of different nanoparticles can be produced by different chemical or physical methods and are available now on the market. Each of these methods has their own advantages and disadvantages. During the last decade, laser processing has been used very successfully for production of nanoparticles. In this lecture I will show how, by using the laser technique, we produce nanoparticles of different materials (metals, oxides, semiconductors, carbon and others), different sizes (from several nm to submicron), different shapes and structures. I will briefly explain the main idea used in our original method. I will also observe briefly the modern methods and apparatuses used for nanoparticle charachterization.
