ACS Appl Mater Interfaces. 2016 Dec 28. doi: 10.1021/acsami.6b15361. [Epub ahead of print]Photonic crystals (PCs) have recently attracted considerable attention, with much effort devoted to photonic bandgap (PBG) control for varying the reflected color. Here, fabrication of a modulated one-dimensional (1D) anodic aluminum oxide (AAO) PC with a periodic porous structure is reported. The PBG of the fabricated PC can be reversibly changed by switching the ultraviolet (UV) light on/off. The AAO nanopores contain a mixture of photo-responsive liquid crystals (LCs) with irradiation-activated cis/trans photo-isomerizable azobenzene. Read More
