Abstract	We present here analysis of the discharge characteristics of a non-thermal plasma jet, where the surrounding gas condition of the plasma jet is precisely controlled in open air. The mixing of the surrounding gas into the plasma jet markedly changes the discharge characteristics: the optical emission intensity of Ni2+ linearly increases with an increase in gas flow ratio of N2 to O2 in the surrounding gas. Our experiments clearly demonstrate that the plasm jet could be controlled from O2 main discharge to N2 main discharge by changing the surrounding gas condition even in open air.
