Abstract：The emission spectra of air dielectric barrier discharge were measured through dielectric barrier discharge experiment system, and the influence of argon fraction on the emission spectra of air dielectric barrier discharge was studied in the present paper. In the wavelength range of 280~500 nm, the second positive band system of nitrogen N2(Ｃ 3Πｕ-Ｂ 3Πｇ) and the first negative band system of nitrogen ion N+2(B 3Σ＋ｕ-Ｘ 2Σ＋ｇ) were found. Adding 10% argon under the same conditions, initial discharge voltage reduced from 26 to 23 kV, both dielectric barrier discharge and its emission spectra intensity were enhanced, and the full width at half maximum increased. With increasing argon fraction, the trends of each nitrogen second positive band system line were different and two nitrogen ion first negative band system lines (391.44 and 427.81 nm) were reduced.
