Tracking ultrafast excited-state bond-twisting motion in solution close to the Franck-Condon point.
TL;DR: In the higher-viscosity solvent, propanol, wavelength-dependent oscillatory features are superimposed to the overall chirp structure pointing to the importance of excited-state vibrational coherences for the dumping process.

Recombination dynamics in aerotaxy-grown Zn-doped GaAs nanowires.
Wei Zhang,Fangfang Yang,Maria E. Messing,Kilian Mergenthaler,Mats-Erik Pistol,Knut Deppert,Lars Samuelson,Martin Magnusson,Arkady Yartsev +8 more
TL;DR: It is found that the photo-luminescence (PL) lifetime of intrinsic GaAs NWs is significantly increased after growing an AlGaAs shell over them, indicating that an Al GaAs shell can effectively passivate the surface of aerotaxy-grown GaAsNWs.

Dynamics of charge separation in the excited-state chemistry of protochlorophyllide
Benjamin Dietzek,Stefanie Tschierlei,Robert Hanf,Sonja Seidel,Arkady Yartsev,Michael Schmitt,Gudrun Hermann,Juergen Popp +7 more
TL;DR: In this paper, the excited-state dynamics of PChlide, the substrate of the enzyme protochlorophyllide oxidoreductase, was examined by means of time-resolved absorption anisotropy and magic-angle measurements.

Rosemann,Iria Bolaño Losada,Catherine Johnson,Pavel Chábera,Aleksandra Ilic,Jesper Schwarz,Arvind Kumar Gupta,Jens Uhlig,Tore Ericsson,Lennart Häggström,Ping S. Huang,Jesper Bendix,Daniel Strand,Arkady Yartsev,Reiner Lomoth,Petter Persson,Kenneth Wärnmark +19 more
TL;DR: Fe(III) hexa-NHC complexes with N-heterocyclic carbene (NHC) ligands belong to the rare examples of Earth-abundant transition metal complexes with long-lived luminescent charge transfer excited states that enable applications as photosensitizers for charge separation reactions as discussed by the authors .

Charge Carrier Dynamics of Polymer:Fullerene Blends: From Geminate to Non‐Geminate Recombination
Dimali A. Vithanage,Ergang Wang,Zhongqiang Wang,Fei Ma,Olle Inganäs,Mats Andersson,Arkady Yartsev,Villy Sundström,Torbjörn Pascher +8 more
TL;DR: In this paper, the charge carrier dynamics of a new polymer- fullerene blend were examined on the femtosecond to the millisecond time scale and the full time range was globally fitted using a chemical reaction rate model that includes all key processes, charge generation, energy transfer, charge separation, and recombination, over the full 12 orders of magnitude in time and a factor of 33 in light intensity.
