Spectral Characteristics of Different Kinds of Hexagon Pattern in Evolutionary Process
摘要
Abstract
The spectral characteristics of different kinds of hexagon pattern with the same symmetry in evolutionary process were studied in dielectric barrier discharge by optical emission spectrum. It is found that the discharge undergoes hexagon superlattice pattern, hollow hexagon pattern and hon-eycomb pattern with the increasing of the applied voltage. The electronic density, electron excitation temperature and molecular vibration temperature of the three kinds of patterns were investigated by the broadening of spectral line 696. 5 nm, the relative intensity ratio method of spectral lines of ArⅠ763. 2 nm (2P6→1S5) and Ar Ⅰ772. 1 nm (2P2→1S3) and the emission spectra of nitrogen band of second positive system ( C3Πu→B3Πg ) , respectively. The results show that the electronic density of the hexagon superlattice pattern, hollow hexagon pattern and honeycomb pattern gradually decreases, while the electron excitation temperature and molecular vibration temperature of the three kinds of patterns gradually increase with the applied voltage increasing. It is found that the change of the plasma state has effect on the self-organization of the pattern.关键词
