Emission characteristics of gas-discharge ethanol-vapor plasma

Emission characteristics of a low-temperature ethanol-vapor plasma formed with the use of high-frequency and barrier discharges have been studied. The plasma emission in the spectral range of 300–700 nm was analyzed in detail. The partial pressure of the ethanol vapor was 5.7 kPa. The emission spectra of the ethanol- and argon/ethanol-vapor plasmas strongly differ. In addition, time characteristics of current and emission pulses in a high-frequency discharge in ethanol vapor are presented.
