Purpose of work – development of theoretical foundations for obtaining nanostructures based on metal oxides for use in devices using surface-enhanced Raman spectroscopy (SERS) to amplify the signal when measuring the concentration of explosive substances to a lesser extent by 106 times. Research methods – mathematical models that allow to determine the growth parameters of oxide and carbon nanostructures when changing the control factors in the plasma environment are the methodological basis for solving the problems of the project; studies of nanostructures are carried out by scanning and transmission electron microscopy Results and novelty: first: the method of transformation of 1D nanostructures into 2D nanostructures in glow discharge plasma is theoretically substantiated; the influence of the stage of intermediate precipitation of a noble metal for doubling the length of one-dimensional nanostructures in plasma is theoretically substantiated and experimentally confirmed; proposed experimental methods of forming complex hierarchical 2D and 3D in glow and arc discharge plasma; got further development: methods of forming nanostructures in glow and arc discharge; methods of protecting the growth zone of nanostructures from the negative effects of plasma; the essential factors of the formation of nanostructures, and the conditions for the transition to structures of another dimension.
