摘要：

Slot microplasma in low temperature, atmospheric pressure air is developed for applications in surface, gas, or biomedical treatments. Dielectric barrier discharge between two parallel aluminum (Al) rods covered with nanoporous alumina films, similar to 60 mu m thick and mean pore diameters of similar to 40 nm, is driven by 20 kHz ac power. The glow microplasma is stable and spatially uniform, using 2-10 W, in the gap of 100-500 mu m between the rods of 3 mm diameter and 5 cm long. This type of slot discharge operational in ambient temperature atmospheric pressure air can provide large-scale nonthermal plasma for any applications requiring continuous low temperature treatments.
