Plasmon-Enhanced Photocatalytic Activity of Cadmium Sulfide Nanoparticle Immobilized on Silica-Coated Gold Particles
Tsukasa Torimoto,Hiroki Horibe,Tatsuya Kameyama,Ken-ichi Okazaki,Shigeru Ikeda,Michio Matsumura,Akira Ishikawa,Hajime Ishihara +7 more
TL;DR: In this paper, the photocatalytic activity of CdS nanoparticles for H2 evolution was greatly dependent on the distance between Cs and Au particles, due to the locally enhanced electric field produced by photoexcitation of the localized surface plasmon resonance (LSPR) peak of Au particles.
Journal ArticleDOI
Remarkable photoluminescence enhancement of ZnS–AgInS2 solid solution nanoparticles by post-synthesis treatment
Tsukasa Torimoto,Shoji Ogawa,Tomohiro Adachi,Tatsuya Kameyama,Ken-ichi Okazaki,Tamaki Shibayama,Akihiko Kudo,Susumu Kuwabata +7 more
TL;DR: The photoluminescence intensity of ZnS-AgInS(2) solid solution nanoparticles was remarkably enhanced by increasing the heating temperature to 180 degrees C, above which the emission was simply diminished, while ZNS coating of the particles resulted in further enhancement of PL intensity, giving the highest quantum yield.
Journal ArticleDOI
Preparation and photoelectrochemical properties of densely immobilized Cu2ZnSnS4 nanoparticle films
Tatsuya Kameyama,Takaaki Osaki,Ken Ichi Okazaki,Tamaki Shibayama,Akihiko Kudo,Susumu Kuwabata,Tsukasa Torimoto +6 more
TL;DR: Colloidal Cu2ZnSnS4 (CZTS) nanoparticles with sizes of 5-6 nm were successfully synthesized through thermal reactions of metal acetate and sulfur in high-temperature oleylamine solution.
Journal ArticleDOI
Tunable photoluminescence from the visible to near-infrared wavelength region of non-stoichiometric AgInS2 nanoparticles
Meilin Dai,Shoji Ogawa,Tatsuya Kameyama,Ken Ichi Okazaki,Akihiko Kudo,Susumu Kuwabata,Yasuyuki Tsuboi,Tsukasa Torimoto +7 more
TL;DR: In this article, a non-stoichiometric AgInS2 (AIS) semiconductor particles were synthesized by the thermal decomposition of single-source precursors in solutions of two kinds of primary amines (oleylamine and octylamine), where the Ag content in the resulting nanoparticles was controlled by adjusting the chemical composition of the precursor used, in which the mole ratio of Ag+ to total metal ions was varied from 0.1 to 0.7.
Journal ArticleDOI
Photofunctional Materials Fabricated with Chalcopyrite-Type Semiconductor Nanoparticles Composed of AgInS2 and Its Solid Solutions
TL;DR: Tunability of optical properties has considerably contributed to recent advances in photofunctional applications of chalcopyrite-type semiconductor nanoparticles to sensors, photocatalysts, and solar cells.
