Název v původním jazyce

ICCD microscopy and spectroscopy of a single surface coplanar DBD micro-discharge driven in N2, O2 and in synthetic air at atmospheric pressure

Popis výsledku v původním jazyce

Techniques of the ICCD microscopy, ICCD spectrometry and multi-channel photon-counting with nanosecond time resolution were employed to study basic radiative characteristics of a single isolated micro-discharge generated in a surface DBD reactor with nanosecond time resolution. Fast ICCD was utilized to register images and spectrally-resolved emission of individual micro-discharges synchronously either with high voltage waveforms or with micro-discharge current pulses. Build-up and decay time constantsof several excited states together with streamer channel diameter were obtained for an isolated micro-discharge which is essentially free of an interference that might be caused by reactive species produced and left by preceding discharges. Such characteristics provide important benchmarks for more complex surface DBD geometries where accumulation of species capable of affecting the physical chemistry of micro-discharges readily occurs.
