| Description | The diffuse coplanar surface barrier discharge (DCSBD) has unique properties among others dielectric barrier discharges such as the generation of thin layer of non-equilibrium atmospheric pressure plasma with high power densities (up to 100W/cm3). Among various parameters, which influence properties of the DCSBD, the temperature of electrodes can play a crucial role not only for intensive cooling of the electrode system. But the temperature could also influence significantly processes running during numerous possible technical applications. The electrodes of the DCSBD were cooled/heated by means of Peltiere cells and the discharge spectra were recorded. Using optical emission spectroscopy the variation of plasma parameters was studied. It was found, that the vibrational temperature as well as rotational temperature changes significantly even for relatively narrow electrode temperature range. |
