Microstructural Control of Aluminum/aluminum Oxide Electrochemistry: Aluminum/aluminum Oxide Photonic Devices

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.
