Abstract

The experimental results concerning the modification of the NeI emission spectra as well as the time evolution of both the discharge current and the yellow line intensity with the wavelength of 585.3 nm, at the H₂ and/or SF₆ addition to the Ne+1%Xe Penning mixture, are obtained for the narrow gap dielectric barrier discharges. The H₂ and SF₆ contribution to the depletion of the lower level 1s₂ through Penning collisions and also the hydrogen participation to the feeding of the upper level 2p₁ of the optical transition 2p₁−1s₂ of the neon have been revealed.
