Emission spectroscopic study of an analytical glow discharge with plane and hollow cathodes: titanium and iron in argon discharge
Original language description
Ti and Fe emission spectra from plane and hollow cathode glow discharges in argon were measured by high resolution Fourier Transform spectrometer and analyzed. Analyte ionization in both discharge modes is dominated by charge transfer (CT) between Ar+ ions and neutral analyte atoms, while this process is more pronounced in a plane cathode than hollow cathode discharge. Radiative decay of the CT-excited levels is found to cause overpopulation of long-lived ground term and metastable analyte ions, relative to the equilibrium number densities that would be expected from the Saha-Boltzmann distribution. This overpopulation is found to spread into high-energy levels of neutral atoms by collisional 3-body recombination with electrons. The analysis of the spectra is based on experimental Boltzmann plots, transition rate diagrams and intensity ratios of emission lines measured in both discharge configurations. Uncertainty propagation in the data processing procedures is analyzed and described.
