| Outline of Final Research Achievements |
We investigated diagnostic methods which can be used for fundamental studies of plasma-liquid interaction. We confirmed that two-dimensional laser-induced fluorescence kept its sensitivity at the vicinity to the interface between plasma and solid (or liquid). It was impossible to observe the region with high densities of liquid-phase reactive species, which are transported from plasma, by laser-induced fluorescence of phenol and the color reaction of titanium sulfate. On the other hand, we observed blue chemiluminescence from alkaline solutions with the addition of luminol. The region with the chemiluminescence was very thin, and was located just below the plasma-irradiated interface. It has been suggested that the chemiluminescence of luminol is useful for the detection of plasma-induced short-lived reactive species in liquids.
