What is it about?

Cold atmospheric pressure plasma jets have a number of applications such as cancer treatment, wastewater treatment, and much more. Oxygen is a critical species for many of these applications. In this work, we report on the observation of a seldom seen oxygen line and highlight its importance to various subject areas in science.

Why is it important?

Atomic oxygen is routinely created in atmospheric pressure plasmas but not in the particular state that we observe. Our findings highlight an uncommon phenomenon which has implications for astrophysical research on comets and many technological applications.

Perspectives

This project was conducted on our own time, sometimes with our own funds. The observation of the auroral green line was a most exciting moment. Given the impact of this particular state of oxygen in technological applications as well as fundamental science, we will continue to expand on this project.

This was the first work using all independent researcher team mainly postdocs using our own funding. Auroral formation is quite a general phenomenon and studied long been but haven't seen visually in laboratory devices in atmospheric condition. This work enable to open a new area of research. Further, atomic oxygen has strong industrial applications.

This work sets an example that sometimes a small thought can create a new interesting field and benefits several researchers and communities.
