低圧マイクロ波放電窒素プラズマにおけるN₂ 1+バンドの放射測定

抄録

Spectroscopic measurements of low-pressure microwave-discharged nitrogen plasma in the wavelength region of 410 to 790 nm were conducted by changing the flow rate and the net incident power of microwave. The N₂ 2+ and N₂⁺ 1－ bands in shorter wavelength region and the N₂ 1+ band in longer wavelength region were observed. In this study, radiation from N₂ B ³Π_g state on v′> 12 in the N₂ 1+ band, which normally observed in such as Lewis-Rayleigh afterglow, was investigated in detail. As a result, it was found that the intensity tends to relatively increase as the flow rate increases.
