Abstract

The pulsed discharge in oxygen and its mixtures to produce singlet delta oxygen has been studied experimentally at gas pressure of 30~ 936mBar. As singlet sigma state of oxygen O₂(b¹Σ_g⁺) and atomic oxygen O have great influence on the yield of singlet delta oxygen O₂(a¹▵_g), the visible spectrum of O₂(b¹Σ_g⁺) at 762nm and O at 778nm have been measured, and the effects of argon, helium and carbon monoxide have been discussed. The electric stability was better in O₂-He than in O₂-Ar mixtures, while it could be increased quickly with a small amount of CO. In O₂-He mixtures more oxygen were decomposed than in O₂-Ar mixtures, while adding CO the decomposition was reduced, the amount of atomic oxygen was decreased, and the O₂(b¹Σ_g⁺) was increased comparatively. The time-resolved spectrum of the plasma has also been measured. The life-time of atomic oxygen was longer than O₂(b¹Σ_g⁺)'s, and it could be shorten with argon.
