  • Ar/CH 3 OH and Ar/N 2 /CH 3 OH plasma jets were generated at atmospheric pressure by dual-frequency excitations. Two different cases were studied with focus laid on the generation of CN radicals. In one case Ar gas passed through a bubbler with saturated methanol steam but without addition of N 2 (Ar/CH 3 OH plasma). In the other case N 2 passed through the bubbler with saturated methanol steam (Ar/N 2 /CH 3 OH plasma). The optical emission lines of CN radicals have been observed in these two cases of plasma discharges. The addition of N 2 can significantly increase the optical emission intensity of CN bands.
