Abstract

At the atmospheric pressure, argon plasma jet was
obtained for 20 kHz frequency, 8 kV voltage and different flow rate in the
DBD-like system. The optical emission spectra of these jets were taken.
Spectral lines of discharges experimentally obtained were compared with
spectral lines in NIST (National Institute of Standards and Technology)
database. Atmospheric pressure plasmas are optically thin. Therefore, the line
intensity ratio method can be used by determining suitable spectral lines. In
general, the intensity of a spectral line is a function of both electron
temperature and density. While determining these spectral lines, those
sensitive to electron temperature were selected. The spectral lines, which are
sensitive to electron temperature, depend on the difference between the
excitation energy levels and the transition probability ratios. As a result,
the electron temperature of argon jet was tried to be determined by line
intensity-ratio method.
