Abstract
A new approach to dielectric barrier discharge plasma jet at atmospheric pressure is presented in this paper. There are few studies have investigated the optical emission spectroscopy diagnosis of acetone species in intermediate frequency argon/acetone plasma at atmospheric pressure. Argon/acetone plasma jet was generated from a nozzle using an AC discharge in intermediate frequency at atmospheric pressure. The spectral lines of argon and acetone plasma emission were obtained and analyzed by using HR2000 spectral diagnosis equipment. It is significant for the application of optical emission spectroscopy diagnosis of volatile organic reagent in argon plasma and is important to the concept of plasma polymerization of volatile organic reagent. There exist large differences in the activity species of acetone plasma at atmospheric pressure and under vacuum condition and oxygen is the most important influencing factor. In addition, the spectral line 706.35 and 727.38 nm are chosen to estimate the electron excitation temperature. The experimental results indicate that spectral diagnosis has been proved a workable method.
