Journal ArticleDOI
Design Principles for Trap-Free CsPbX3 Nanocrystals: Enumerating and Eliminating Surface Halide Vacancies with Softer Lewis Bases.
David P. Nenon,Kimo Pressler,Jun Kang,Brent A. Koscher,Jacob H. Olshansky,Wojciech T. Osowiecki,Matthew A. Koc,Lin-Wang Wang,A. Paul Alivisatos +8 more
TL;DR: This work provides a systematic framework for preparing highly luminescent CsPbX3 nanocrystals with variable compositions and dimensionalities, thereby improving the fundamental understanding of these materials and informing future synthetic and post-synthetic efforts toward trap-free CspbX2 nanocrystal efforts.
Journal ArticleDOI
Efficiency of hole transfer from photoexcited quantum dots to covalently linked molecular species.
TL;DR: The results show the potential of QD systems to drive desirable oxidative chemistry without undergoing oxidative photodegradation, and the merits of a system where ill-defined nonradiative channels are suppressed and well-definedNonradiatives channels are engineered and quantified are demonstrated.
Journal ArticleDOI
Surface- vs Diffusion-Limited Mechanisms of Anion Exchange in CsPbBr3 Nanocrystal Cubes Revealed through Kinetic Studies
Brent A. Koscher,Noah D. Bronstein,Jacob H. Olshansky,Yehonadav Bekenstein,A. Paul Alivisatos +4 more
TL;DR: These results represent the first steps toward developing a microkinetic description of the anion exchange, with implications not only for understanding the lead halide perovskites but also for nanoscale ion exchange in general.
Journal ArticleDOI
Hole Transfer from Photoexcited Quantum Dots: The Relationship between Driving Force and Rate.
TL;DR: The observed relationship between driving force and rate for interfacial hole transfer from quantum dots (QDs) can be used to design QD-molecular systems that maximize interfacial charge transfer rates while minimizing energetic losses associated with the driving force.
Journal ArticleDOI
Hole Transfer Dynamics from a CdSe/CdS Quantum Rod to a Tethered Ferrocene Derivative
Kartick Tarafder,Kartick Tarafder,Yogesh Surendranath,Jacob H. Olshansky,Jacob H. Olshansky,A. Paul Alivisatos,A. Paul Alivisatos,Lin-Wang Wang +7 more
TL;DR: Hole transfer between a CdSe/CdS core/shell semiconductor nanorod and a surface-ligated alkyl ferrocene and the results suggest that holes may be extracted more efficiently from well-passivated nanocrystals by reducing the energetic driving force for hole transfer, thus minimizing energetic losses.
