The discharge electrode geometry based on machinable glass–ceramic was optimized in order to get a system free of the circulating dielectric liquids that are frequently used to insulate and cool metallic electrodes. The build-up and decay of UV–vis–NIR emission by a single micro-discharge unaffected by concurrent or preceding discharge events was inspected during the first 10 µs of the micro-discharge evolution in nitrogen and in synthetic air. Obtained emission waveforms show a great similarity between the surface and volume streamers. The streamer volume-averaged N2(A) concentrations of ~8 x 1014 cm−3 were estimated at t = 1 µs decay time and concentrations of ~(2–4) x 1015 cm−3 were estimated during the streamer propagation phase in nitrogen.
