Low-energy visible light was converted into heat energy through the excitation of the localized surface plasmon resonance of gold nanospheres excited by upconverted emission based on triplet–triplet annihilation of organic molecules. This system al

Enhancement of Raman scattering from single-walled carbon nanotubes on densely-arranged two-dimensional gold nanoparticle assemblies

Autor: Koji Uchida, Joe Otsuki, Kosuke Sugawa, Shuto Igari, Wataru Inoue

Publikováno v: Molecular Crystals and Liquid Crystals. 654:151-156

We investigated surface-enhanced Raman scattering properties of single-stranded DNA-functionalized single-walled carbon nanotubes (ssDNA-SWCNTs) modified on densely-arranged two-dimensional Au nanoparticle assemblies. The ssDNA-SWCNTs was prepared by

Development of Plasmonic Cu2O/Cu Composite Arrays as Visible- and Near-Infrared-Light-Driven Plasmonic Photocatalysts

Publikováno v: Langmuir. 33:5685-5695

We describe efficient visible- and near-infrared (vis/NIR) light-driven photocatalytic properties of hybrids of Cu2O and plasmonic Cu arrays. The Cu2O/Cu arrays were prepared simply by allowing a Cu half-shell array to stand in an oxygen atmosphere f

Plasmonic Silver Nanoprism-Induced Emissive Mode Control between Fluorescence and Phosphorescence of a Phosphorescent Palladium Porphyrin Derivative

Autor: Kotomi Kanakubo, Hiroki Wakui, Ryuzi Katoh, Hironobu Tahara, Shuto Igari, Naoto Takeshima, Misa Fukushima, Shota Jin, Kosuke Sugawa, Joe Otsuki, Yutaro Hayakawa, Kyo Tokuda, Kouichi Takase

Publikováno v: ACS nano. 13(11)

We have succeeded in significantly enhancing fluorescence from intrinsically phosphorescent palladium octaethylporphyrin (Pd-porphyrin) that has an intersystem crossing efficiency of ∼1 by using silver nanoprisms (AgPRs). This was achieved by contr
