We produced an anodic aluminum oxide (AAO) structure with periodic nanopores on the surface of flip-chip blue light-emitting diodes (FC-BLEDs). The nanopores had diameters ranging from 73 to 85 nm and were separated by distances ranging from approximately 10 to 15 nm. The light extraction efficiency enhancement of the FC-BLEDs subjected to different durations of the second pore-widening process was approximately 1.6–2.9%. The efficiency enhancement may be attributed to the following mechanism: periodic nanopores on the surface of FC-BLEDs reduce the critical angle of total reflection and effective energy transfer from a light emitter into a surface plasmon mode produced by AAO.

Owning to the robust characteristics of diamonds, a nano-tip array structured mold was fabricated with diamond, we can then use this mold to produce anti-reflection (AR) films with nanoimprint lithography. Taking advantage of the self-ordered characteristic of anodic aluminum oxide (AAO), we can obtain the diamond mold by depositing a layer of diamond on the AAO using hot filament chemical vapor deposition (HFCVD). Then taking advantage of the high through-put characteristics of nanoimprint lithography, AR films can be mass produced. The AR films were subjected to reflectivity inspections, a 5.5% reduction in reflectivity was obtained.
