Self-assembled porous anodic alumina shows a random distribution of domains, each of them with a very definite triangular pattern, constituting a quasi-random structure. The observed stop bands are similar to those of photonic quasicrystals or random structures. As the pores of nanoporous anodic alumina can be infiltrated with noble metals, nonlinear or active media, it makes this material very attractive and cost-effective for applications including inhibition of spontaneous emission, random lasing, LEDs and biosensors.Keywords: Active media; Anodic alumina; Finite difference time domains; Nano-porous; Photonic quasicrystal; Photonic stop band; Porous anodic alumina; Quasi-random; Random distribution; Random lasing; Random structures; Self-assembled; Stop-bands; Biosensors; Finit Nanoporous anodic alumina; Photonic crystals; Photonic stop bands; Quasi-random structures201210.1016/j.photonics.2012.02.0032016-02-24
