Optical Diagnosis of Large Area Homogenous Dielectric Barrier Discharge in Nitrogen at Atmospheric Pressure
In the present study, dielectric barrier homogenous discharge in nitrogen was obtained between large plate electrodes (150×300 mm) at atmospheric pressure and the emission spectra of N2(C3Πu→B3Πg) and N+2(B2Σ+u→X2Σ+g 0-0 391.4 nm) were recorded. It was found that both the emission intensities of N2(C3Πu→B3Πg) and N+2(B2Σ+u→X2Σ+g 0-0 391.4 nm) increase with the rising of the applied voltage and the driving frequency, respectively. The main physicochemical formation mechanism of N+2(B2Σ+u) in N2 and He+N2 mixtures homogenous discharge was discussed, and the penning ionization was proved to be the dominant formation mechanism.
