Ultrafast plasmon-induced electron transfer from gold nanodots into TiO2 nanoparticles.
TL;DR: By using femtosecond transient absorption spectroscopy with visible pump and IR probe to observe generation of injected electrons, plasmon-induced electron transfer from 10 nm gold nanodots to TiO2 nanocrystalline film is observed.
Journal ArticleDOI
Efficiencies of Electron Injection from Excited N3 Dye into Nanocrystalline Semiconductor (ZrO2, TiO2, ZnO, Nb2O5, SnO2, In2O3) Films

TL;DR: In this paper, the efficiency of electron injection from excited N3 dye (cis-bis-(4,4‘)-dicarboxy-2,2‘-bipyridine) dithiocyanato ruthenium(II), Ru(dcbpy)2 (NCS)2), into various nanocrystalline semiconductor (ZrO2, TiO2 and ZnO, ZnNO, Nb2O5, SnO2 or In2O3) films was studied by
Journal ArticleDOI
Identification of Reactive Species in Photoexcited Nanocrystalline TiO2 Films by Wide-Wavelength-Range (400−2500 nm) Transient Absorption Spectroscopy
Toshitada Yoshihara,Ryuzi Katoh,Akihiro Furube,Yoshiaki Tamaki,Miki Murai,Kohjiro Hara,Shigeo Murata,Hironori Arakawa,†,‡ and,Masanori Tachiya +8 more
TL;DR: In this paper, a superposition of the free and trapped electron spectra was obtained by subtracting the electron spectrum from the transient absorption spectrum, and the spectrum of trapped holes was obtained.
Journal ArticleDOI
Direct observation of reactive trapped holes in TiO2 undergoing photocatalytic oxidation of adsorbed alcohols: evaluation of the reaction rates and yields.
TL;DR: To investigate the primary process of photocatalytic oxidation of TiO2, interfacial charge-transfer reaction of trapped holes formed in nanocrystallineTiO2 films by UV irradiation was directly measured by highly sensitive femtosecond and nanosecond transient absorption spectroscopy under low intensity excitation condition to avoid fast electron-hole recombination.
Journal ArticleDOI
Partially diffusion‐controlled recombination
Hisatake Sano,Masanori Tachiya +1 more
TL;DR: In this paper, the authors extended Tachiya's method for treating totally diffusion-controlled recombination of a pair of particles to partially diffusion controlled recombination, and derived the differential equation satisfied by the survival probability of the pair.
