One-Step Anodization Preparation and Photoluminescence Property of Anodic Aluminum Oxide with Nanopore Arrays
Anodic aluminum oxide (AAO) film with nanopore arrays was prepared by one-step anodization of highly pure aluminum foil. Morphology, structure and photoluminescence property of AAO were characterized. Results showed that AAO owned honeycomb structure which was characterized by close-packed arrays of columnar hexagonal cells, each containing a central pore normal to the substrate. There were three peaks at around 370, 385 and 470 nm in the PL spectrum of AAO, which should be mainly attributed to the oxygen vacancies.
