Journal ArticleDOI
Tuning the Excitonic and Plasmonic Properties of Copper Chalcogenide Nanocrystals
Ilka Kriegel,Chengyang Jiang,Jessica Rodríguez-Fernández,Richard D. Schaller,Richard D. Schaller,Dmitri V. Talapin,Dmitri V. Talapin,Enrico Da Como,Jochen Feldmann +8 more
TL;DR: The results demonstrate that copper chalcogenide NCs offer the unique property of holding excitons and highly tunable LSPs on demand, and hence they are envisaged as a unique platform for the evaluation of exciton/LSP interactions.
Journal ArticleDOI
Plasmonic doped semiconductor nanocrystals: Properties, fabrication, applications and perspectives
TL;DR: In this article, the authors highlight the recent advances in the synthesis of various different plasmonic semiconductor NCs with LSPRs covering the entire spectral range, from the mid-to the NIR.
Journal ArticleDOI
Shedding light on vacancy-doped copper chalcogenides: shape-controlled synthesis, optical properties, and modeling of copper telluride nanocrystals with near-infrared plasmon resonances.
Ilka Kriegel,Jessica Rodríguez-Fernández,Andreas Wisnet,Hui Zhang,Christian Waurisch,Alexander Eychmüller,Aliaksei Dubavik,Aliaksei Dubavik,Alexander O. Govorov,Jochen Feldmann +9 more
TL;DR: It is shown that copper telluride NCs with well-defined morphologies (spheres, rods, tetrapods) can be prepared via cation exchange of preformed CdTe NCs while retaining their original shape, suggesting that holes in the valence band of Cu(2-x)Te cannot be described as fully free particles and that the effects of localization of holes are important.
Journal ArticleDOI
Optimal metal domain size for photocatalysis with hybrid semiconductor-metal nanorods.
Yuval Ben-Shahar,Francesco Scotognella,Ilka Kriegel,Luca Moretti,Giulio Cerullo,Eran Rabani,Eran Rabani,Uri Banin +7 more
TL;DR: A combination of transient absorption, hydrogen evolution kinetics and theoretical modelling reveal a non-monotonic behaviour with size of the gold tip, leading to an optimal metal domain size for the most efficient photocatalysis.
Journal ArticleDOI
Charge Transfer Excitons in Polymer/Fullerene Blends: The Role of Morphology and Polymer Chain Conformation
Markus Hallermann,Ilka Kriegel,Enrico Da Como,Josef Berger,Elizabeth von Hauff,Jochen Feldmann +5 more
TL;DR: In this paper, it was shown that carrier recombination through charge transfer excitons between conjugated polymers and fullerene molecules is mainly controlled by the intrachain conformation of the polymer, and to a limited extent by the mesoscopic morphology of the blend.
