Journal ArticleDOI
Direct observation of triplet energy transfer from semiconductor nanocrystals.
TL;DR: It is demonstrated by transient absorption spectroscopy that cadmium selenide semiconductor nanoparticles, selectively excited by green light, engage in interfacial Dexter-like triplet-triplet energy transfer with surface-anchored polyaromatic carboxylic acid acceptors, extending the excited-state lifetime by six orders of magnitude.
Journal ArticleDOI
Enhanced Lifetime of Excitons in Nonepitaxial Au/CdS Core/Shell Nanocrystals
Scott Lambright,Evgeniia Butaeva,Natalia Razgoniaeva,Thomas Hopkins,Bryan Smith,Dimuthu Perera,Jonathan Corbin,Elena Khon,Rebekah Thomas,Pavel Moroz,Andrey S. Mereshchenko,Alexander N. Tarnovsky,Mikhail Zamkov +12 more
TL;DR: In this paper, the lifetime of excitons in the CdS shell (τ ≈ 300 ps) is shown to be much longer than that of conventional, reduction-grown Au/CdS heteronanostructures.
Journal ArticleDOI
Mapping the exciton diffusion in semiconductor nanocrystal solids.
Natalia Kholmicheva,Pavel Moroz,Ebin Bastola,Natalia Razgoniaeva,Jesus Bocanegra,Martin Shaughnessy,Zack Porach,Dmitriy Khon,Mikhail Zamkov +8 more
TL;DR: An experimental technique for mapping the motion of excitons in semiconductor nanocrystal films with a subdiffraction spatial sensitivity and a picosecond temporal resolution is developed.
Journal ArticleDOI
Photocatalytic Applications of Colloidal Heterostructured Nanocrystals: What's Next?
TL;DR: The main scope of present-day efforts targets the improvement of interstitial charge transfer pathways across the chromophore-catalyst assembly through the design of high-quality stoichiometric interfaces.
Journal ArticleDOI
One-Dimensional Carrier Confinement in “Giant” CdS/CdSe Excitonic Nanoshells
Natalia Razgoniaeva,Pavel Moroz,Mingrui Yang,Darya S. Budkina,Holly Eckard,Marissa Augspurger,Dmitriy Khon,Alexander N. Tarnovsky,Mikhail Zamkov +8 more
TL;DR: An inverse energy-gradient core/shell architecture supporting the quantum confinement in nanoparticles larger than the exciton Bohr radius is developed, which reveals a characteristic size-dependent behavior tunable via the shell thickness with associated quantum yields in the 4.4-16.0% range.
