Quantum Dot on a Rope

Journal of the American Chemical Society, 2002
The conjugation of nanoparticles (NPs) typically yields supramolecular materials which are fairly rigid, and the electronic coupling between the NP and other structural units of these compounds is fixed by covalent bonds. Here, we report on a novel bichromophor system constructed from a quantum dot tethered to a semiconducting polymer, which ...

Caged Quantum Dots

Journal of the American Chemical Society, 2008
Photoactivatable organic fluorophores and fluorescent proteins have been widely adopted for cellular imaging and have been critical for increasing temporal and spatial resolution, as well as for the development of superresolution microscopy techniques.

Photochromic quantum dots

Izvestiya vysshikh uchebnykh zavedenii. Fizika, 2021
The analysis of the results of fundamental and applied research in the field of creation of photochromic nanoparticles of the "core-shell" type, in which semiconductor nanocrystals - quantum dots were used as a core, and the shell included physically or chemically sorbed molecules of photochromic thermally relaxing (spiropyrans, spirooxazines ...

From quantum dot to quantum dot

Science, 2016
Materials Science A wide range of materials can now be synthesized into semiconducting quantum dots. Because these materials grow from solutions, there is scope to combine quantum dots into devices by using simple, low-cost manufacturing processes. Kagan et al.

Designing quantum dots and quantum-dot solids

Physica E: Low-dimensional Systems and Nanostructures, 2001
Abstract To design nanocrystal nanosystems, a theory for nanocrystals is needed which can be applied to nanocrystals with atomic-scale variations in composition, structure and shape. We present an empirical tight-binding theory for nanocrystal heteronanostructures.

Stability of Quantum Dots, Quantum Dot Films, and Quantum Dot Light‐Emitting Diodes for Display Applications

Advanced Materials, 2019
AbstractQuantum dots (QDs) are being highlighted in display applications for their excellent optical properties, including tunable bandgaps, narrow emission bandwidth, and high efficiency. However, issues with their stability must be overcome to achieve the next level of development. QDs are utilized in display applications for their photoluminescence (

Quantum Soldering of Individual Quantum Dots

Angewandte Chemie International Edition, 2012
Making contact to a quantum dot: Single quantum-dot electronic circuits are fabricated by wiring atomically precise metal chalcogenide clusters with conjugated molecular connectors. These wired clusters can couple electronically to nanoscale electrodes and be tuned to control the charge-transfer characteristics (see picture).
