The plasma produced by a nano pulsed surface dielectric barrier discharge (SDBD) is investigated experimentally by means of time-resolved optical emission spectroscopy. The relative populations of the most intense radiating species is determined with an in-house code for emission spectroscopy. The possibility to use low-lying states such as N2(B) and argon (2p) to characterize kinetic processes in the plasma at low electric field is demonstrated.
