Název v původním jazyce

Emission spectroscopic diagnostics of weakly ionized argon-diluted plasmas: glow discharge and inductively coupled plasma

Popis výsledku v původním jazyce

An extensive study of Mn, Fe, Ti, Cr, Cu emission spectra from a Grimm-type glow discharge and an inductively coupled plasma (ICP), in argon, was performed, using the formalism of population functions (experimental Boltzmann plots) and transition rate diagrams. Emission characteristics of both spectral sources were compared. In both discharges the excitation of neutral metal atoms (Me I) is dominated by electron impact (EI) and in the excitation of singly charged ions (Me II) the charge transfer between Ar+ ions and Me I plays a significant role, especially in GDOES. Deviations from local thermodynamic equilibrium (LTE) were identified and classified. Experimental ‘excitation temperatures’ follow a pattern predicted by computer simulations with a collisional-radiative model: they are lower than the actual electron temperature, while this deviation is greater for the Me I system than Me II.n
