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 ...

Designing quantum dots and quantum-dot solids
Physica E: Low-dimensional Systems and Nanostructures, 2001Abstract 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.

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 ...

From quantum dot to quantum dot
Science, 2016Materials 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.

Bioluminescence is widely used for in vivo imaging of nude mice. By conjugating luciferase protein to quantum dots, bioluminescence resonance energy transfer (BRET) turns these useful fluorophores into a new class of bioluminescent probe.

A micrometer-sized spherical microcavity, the photonic dot, is made from semiconductor nanocrystals, the quantum dots. The coupling of electronic and photonic states is demonstrated for a single photonic dot by the observation of whispering gallery modes in the spectrum of spontaneous emission of the embedded CdSe quantum dots.

Quantum dots and nanocomposites
WIREs Nanomedicine and Nanobiotechnology, 2010AbstractQuantum dots (QDs), also known as semiconducting nanoparticles, are promising zero‐dimensional advanced materials because of their nanoscale size and because they can be engineered to suit particular applications such as nonlinear optical devices (NLO), electro‐optical devices, and computing applications.
