Effect of O2 into N2 Afterglows in RF and Corona Discharges

🌟 How Oxygen Affects Nitrogen Plasma Afterglows! 🔬⚡

Plasma scientists are unlocking the secrets of N₂-O₂ afterglows, revealing how oxygen changes the behavior of nitrogen-based plasmas. This research is crucial for applications in industrial coatings, environmental science, and plasma-based technologies! 🚀

🔬 Key Findings:
✅ N & O atom measurements – Researchers tracked how nitrogen and oxygen atoms behave when mixed in different plasma conditions.
✅ Oxygen’s impact on nitrogen species – Adding just 1-4% O₂ to N₂ plasma caused a big drop in nitrogen atom density, while oxygen atom density stayed mostly the same.
✅ Early vs. Late Afterglows – In RF plasmas, oxygen atoms (O) were more disruptive to nitrogen activity than O₂ molecules, proving their strong effect on plasma chemistry.
✅ Corona Plasma Mystery – At atmospheric pressure, an N₂O excimer was detected, but in much lower amounts than active nitrogen species, revealing how oxygen impurities influence plasma properties.

💡 Why Does This Matter?
Understanding how oxygen alters nitrogen plasma behavior helps improve plasma-based industrial processes, environmental applications, and advanced surface treatments! 🌍✨
