Light excites the quantum dot core, transferring energy to a magnetic manganese ion through ultrafast sub-picosecond spin exchange.

Background The study of low-dimensional systems for quantum technologies has garnered significant attention in the past few years due to their potential in developing the next generation of quantum ...

On today’s You Asked: Quantum dots and what they do, and why PC monitors aren’t as good as TVs.

Flowing quantum dot solutions enhance heat dissipation, enabling stable high-speed pulsed operation and tunable color output for next-generation optical devices.

Colloidal quantum dots are solution-based nanocrystals prized for their unique light-harvesting abilities. Using heat rather than light, scientists have developed a more reliable method for certifying ...

TCL has come under scrutiny this month after testing that claimed to examine three TCL TVs marketed as quantum dot TVs reportedly showed no trace of quantum dots. Quantum dots are semiconductor ...

What are quantum dots? Quantum dots are a type of particle that are chemically produced and stored on a sheet called a film.

As they are so small – just 2–10nm in diameter – a quantum dot’s electrons experience quantum confinement in all three spatial dimensions. Changing the size of a quantum dot changes its properties, in ...

Quantum dots are tiny crystals that scientists can tune to different colours, giving an extra-vivid pop to next-generation TV screens or illuminating tumours inside bodies so surgeons can hunt ...

Quantum dots are a prime example of the way nanotechnology engineers materials at an atomic scale.
