The results of studying the conditions of synthesis and luminescence of aluminum oxide nanoparticles in a plasma of an overstressed nanosecond discharge ignited between aluminum electrodes at an interelectrode distance of 2 mm and air pressure in the range of 50-202 kPa are presented. It was shown that the plasma of the investigated discharge is characterized by a wide luminescence band in the spectral range of 300–430 nm, which is associated with the formation of F and F + centers. The research results can be used in micro-nanotechnology, biomedical engineering to obtain nanostructured alumina substrates, on which other nanodevices and films from biomaterials can be placed. The aim of the work was to establish the possibility of detecting small nanoparticles - aluminum oxide nuclei by emission spectroscopy methods and the synthesis of nanostructured alumina films under atmospheric conditions (without the use of vacuum technology) over a large area.

“…The light transmission spectra of these films were obtained using UV radiation from a deuterium lamp. The methods and technique of this experiment is more fully presented in [34,35]. The transmission of thin chalcopyrite films, in comparison with the transmission of the substrate, decreased by up to four times, and for the film that was synthesized using a discharge in air, it was minimal at atmospheric pressure.…”

The characteristics of an overstressed bipolar discharge with a duration of 100-150 ns in argon and air, which was ignited between copper electrodes in argon, and also between an aluminum electrode and a chalcopyrite (CuInSe2) electrode in air, are presented. In the process of microexplosions of inhomogeneities on the working surfaces of the electrodes in a strong electric field, the vapor of copper, aluminum, and vapor of ternary chalcopyrite are introduced into the interelectrode gap. This creates the prerequisites for the synthesis of thin copper films and the synthesis of films based on quaternary chalcopyrite - CuAlInSe2, which can be deposited on a quartz plate installed near the center of the discharge gap. The optical characteristics of the plasma, as well as voltage pulses across the discharge gap of d = 1–2 mm, current pulses, and pulsed energy contributions to the discharge, have been investigated using emission spectroscopy with a high time resolution. The plasma emission spectra were thoroughly studied, which made it possible to establish the main decay products of the chalcopyrite molecule and the energy states of atoms and singly charged ions of aluminum, copper, and indium, which are formed in the discharge.
