Quantum Dots

Type: Concept

As of November 2026, Quantum Dots has been mentioned in one podcast episode on Cell Press (Jan 2026). Discussed in the context of quantum communication and single photon emission.

Quantum dots (QDs) or semiconductor nanocrystals are semiconductor particles a few nanometres in size with optical and electronic properties that differ from those of larger particles via quantum mechanical effects. They are a central topic in nanotechnology and materials science. When a quantum dot is illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy. In the case of a semiconducting quantum dot, this process corresponds to the transition of an el
