EFFECTS OF LASER RADIATION AND PLASMA ON NOVEL MATERIALS IN THEIR SYNTHESIS, MODIFICATION, AND ANALYSIS

The object of the research are the effects of laser radiation and plasma on novel materials of interest to medicine,industry,electronic industry and environmental monitoring. Lasers are used on materials for intentional modifications of the structural,optical,electrical,and chemical properties,and forming of nano-structures in different atmospheres. This will include Ti-based materials in the form of nanocomposites and nano-alloys. The created intermetallic compounds with W,Al,V,and Ni can contribute to biomedical and IT applications. Special attention will be paid to nanostructures and nanocomposites formed on surfaces of these materials,or modified by laser irradiation,where the generated plasma has a specific effect or is an important precursor. Thus the research into laser effects and processes in plasma is crucially significant to the understanding of the overall processes whose control is desired. Besides laser irradiation of the samples in controlled atmosphere,laser deposition will be a point of research. Changes in chemical composition,structure,morphology,electrical,and optical characteristics will be diagnosed by microscopy,spectroscopy,and profilometry,and the processes in plasma by optical spectroscopy and mass spectrometry. Self-building of equipment is planned for laser deposition and modification,laser desorption in the mass spectrometer,and modulation of the arc plasma. The proposed project unifies the resources and experiences in the research of this type.
