Abstract: In the spectral range 270–900 nm luminescence spectra experimentally investigated plasma jets formed a barrier discharge in atmospheric pressure in an argon-air mixtures, and helium-air. It is shown that the emission spectra generated by the plasma jets are mainly represented by electron-vibration transitions of the second positive system of neutral nitrogen molecules. The radiation powers of these mixtures are compared.

Keywords: argon, helium, air, plasma jet, barrier discharge.
