Polarized images have been prepared using simple laser‐induced melting of aligned nanorods in a polymer film. The technique is easy‐to‐use, cost‐effective, and may be used to render the read‐out either legible or illegible (see Figure). The information content could be increased by creating ordered nanoparticles with different angles of polarization, thereby permitting readout from different layers within the film, which might lead to 3D applications.
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.
