Their size-dependent colors are essentially a naked-eye, ambient-condition visualization of the quantum confinement effect.

A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons, valence band holes, or excitons (bound pairs of conduction band electrons and valence band ...

Quantum dots (QDs) are semiconductor nanocrystals that exhibit unique optical characteristics due to quantum confinement effects, which result in discrete electronic states and size-tunable ...

Semiconducting colloidal quantum dots have garnered tremendous research interest due to their special optical properties, which arise from the quantum confinement effect.

By harnessing the unique interplay of delayed feedback and energy confinement, EQCE redefines the rules of quantum emission control—a leap toward fault-tolerant technologies and the scalable ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Quantum dots beat traditional photosensitizers at their own game. They tackle reactions once thought too tough for ...

The physics of quantum wells is governed by the principles of quantum mechanics. When the thickness of the semiconductor layer is comparable to the de Broglie wavelength of the charge carriers, ...

The quantum size effect in nanomaterials leads to unique electronic, optical, magnetic, and thermal properties, enabling applications in optoelectronics, energy, and medicine.

Moungi Bawendi, Louis Brus and Alexei Ekimov developed and discovered quantum dots, particles whose size governs their properties. By Emma Bubola and Katrina Miller The Nobel Prize in Chemistry ...

Quantum chromodynamics (QCD) is the theoretical framework for studying the forces within atomic nuclei and their constituent protons and neutrons.

Three scientists won the Nobel Prize in Chemistry for their discovery of quantum dots, an entirely new class of material that is used in large-screen TVs and cancer surgery ...
