乙醇掺氮放电大气压等离子体射流的光谱特征研究
Study on the atmospheric pressure plasma jet spectra of N2/CH 3 CH 2 OH
摘要
Abstract
In this work, the atmospheric pressure plasma jets spectra of Ar/CH 3 CH 2 OH and Ar/N2/CH 3 CH 2 OH are investigated.The spectral lines of C,CN,CH and C2 bands are observed in the plasma spectra via optical emission spectroscopy(OES).In the plasma spectrum of the mixture of Ar and ethanol, the molecular spectral lines of C2 at 473.7,5 1 6.4 and 563.5 nm are assigned,and the spectral line at 388.3 nm is characterized to be CN radical.After doping N2 ,the new CN spectral line appears at 422 nm. The spectral line of C2 is only found at 5 1 6.4 nm,and the spectral lines at 473.7 and 563.5 nm disappear. When the content of ethanol keeps constant,with increasing of the nitrogen flow rate,the intensity of CN spectral line increases observably,while the spectral line intensity of C2 is suppressed effectively.关键词
