Abstract:The fully addressable microcavity plasma device, fabricated by the combination of modified electrochemical etching and anodization, is the first to be demonstrated. Intense luminance and luminous efficacies approaching 1800 cd/m2 and 4 lm/W, respectively, have been observed for 50 x 50 to 320 x 160 arrays of microplasma devices with parabolic cross-sectional microcavities and conformal aluminum electrodes, operating in Ne/Xe gas mixtures. In addition, a microchannel plasma device with complex electrode geometries have been fabricated in a single sheet of aluminum foil with an active area of over 30 cm 2. Power consumption as low as 0.8 W with a luminance of 500 cd/m 2 has been observed in 600 Torr of Ne. These devices are promising for advanced displays and backlighting technology.
