Blu-ray-sensitive localized surface plasmon resonance for high-density optical memory.

ABSTRACT: Tunable spectrum-response is desired for efficient photo-energy transformation. Blu-ray (~405 nm) and polarization sensitive Ag/TiO₂ nanocomposite films are thus fascinating in application of fast-response and high-density optical memory device. The Ag/TiO₂ film has the ability of replicating hologram based on optical coherence by laser-stimulated dissolution of Ag nanoparticles (NPs). The rate and efficiency of the dissolution are supposed to be enhanced by introducing uniform and small-sized Ag NPs in TiO₂ nanoporous films. However, no effective methods have been proposed to resolve this issue by now. Here, we develop a simple method of thermal-reduction to obtain high-density, space-dispersed and extremely small-sized Ag NPs in TiO₂ nanoporous
