Journal ArticleDOI
Plasmon-Assisted Photocurrent Generation from Visible to Near-Infrared Wavelength Using a Au-Nanorods/TiO2 Electrode
TL;DR: In this article, the plasmonic photoelectric conversion from visible to near-infrared wavelength without deteriorating photo-electric conversion by using electrodes in which gold nanorods are elaborately arrayed on the surface of a TiO2 single crystal.
Journal ArticleDOI
Near-Infrared Plasmon-Assisted Water Oxidation.
TL;DR: The stoichiometric evolution of oxygen via water oxidation is reported by irradiating a plasmon-enhanced photocurrent generation system with near-infrared light in which gold nanostructures were arrayed on the surface of TiO2 electrode.
Journal ArticleDOI
Surface plasmon resonances in periodic and random patterns of gold nano-disks for broadband light harvesting
TL;DR: It is shown that dipole-dipole interactions contribute to diffract light parallel to the surface as a mean of long-range coupling between the nano-disks, and allows for simpler, lower resolution fabrication, cost-effective in light harvesting for solar cell and sensing applications.
Journal ArticleDOI
Inverse silica opal photonic crystals for optical sensing applications.
Yoshiaki Nishijima,Kosei Ueno,Saulius Juodkazis,Vygantas Mizeikis,Hiroaki Misawa,T. Tanimura,K. Maeda +6 more
TL;DR: This work reports fabrication of inverse silica opal photonic crystal structures from direct polystyrene micro sphere opals using low-temperature sol-gel infiltration of silica, and examines performance of these photonic crystals as environmental refractive index sensors.
Journal ArticleDOI
Super-sensitivity in label-free protein sensing using a nanoslot nanolaser
Shota Kita,Shoji Hachuda,Shota Otsuka,Tatsuro Endo,Yasunori Imai,Yoshiaki Nishijima,Hiroaki Misawa,Toshihiko Baba +7 more
TL;DR: A super-sensitivity for protein is demonstrated, which satisfies the requirements for high-throughput and low-cost sensing and is suggested to arise from the effective trapping of protein in the nanoslot.
