A KHz frequency cold atmospheric pressure argon plasma jet for the emission of O(1S) auroral lines in ambient air
Abstract Creation of the “auroral” green line, a fascinating occurrence commonly observed in the upper atmosphere, has long been a difficult endeavor, especially at atmospheric pressure. Here we report strong emission of the “auroral” green line for the first time in a kHz frequency, linear field at...

Abstract Creation of the “auroral” green line, a fascinating occurrence commonly observed in the upper atmosphere, has long been a difficult endeavor, especially at atmospheric pressure. Here we report strong emission of the “auroral” green line for the first time in a kHz frequency, linear field atmospheric pressure plasma jet system. The device used 99.999% pure argon as a working gas for the plasma generation. Optical emission spectroscopy measurements of the after discharge region show the existence of 557.7 nm emission which corresponds to the transition O( $$^1$$ 1 S)–O( $$^1$$ 1 D). The intensity of the produced green line is strong enough that the entire plasma plume in the ambient air is visible as a green plasma. We provide the chemical reactions of O( $$^1$$ 1 S) production in the plasma and the estimation of the density of the O( $$^1$$ 1 S) metastable state using the kinetic reactions.
