In this study, the fabrication of thin porous anodic aluminum oxide (AAO) templates with controllable thickness of 400-1300 nm is demonstrated. One-step anodizing method is used to generate AAO template with hexagonal porous distributed profile. The pore diameter pore-widening and AAO barrier layer thinned down are investigated. The morphologies and pore structures of the fabricated AAO templates are characterized using FE-SEM images and the transmittance and reflective spectra.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
