Intentionally 'squashing' colloidal quantum dots during chemical synthesis creates dots capable of stable, 'blink-free' light emission that is fully comparable with the light produced by dots made ...

As a result, they have a significantly longer lifetime—which makes them ideal for storing and controlling quantum states and ...

Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made ...

Hybrid structures containing semiconductor quantum dots and metal nanoparticles could lead to better light-emitting diodes and new nonlinear photonic devices. That is according to researchers in China ...

In a quantum-dot set, the changes start with the color of the backlight. The LEDs in most LCD TVs emit white light, but those in quantum-dot televisions emit blue light.

An electron and a hole trapped in the same quantum dot couple together to form an exciton. Conventionally the hole involved is a heavy hole. Light-hole excitons are now observed by applying ...

Quantum dots amplify light with electrical pumping Light amplification with electrically stimulated quantum dots, critical step towards solution-processible laser diodes Date: November 20, 2017 ...

Liquid-based photodetector leverages water molecules for quantum dot enhancement, offering high sensitivity and wavelength-specific customization for optical and medical applications.

The hybrid material exhibited enhanced light-harvesting properties through the absorption of light by the quantum dots and their energy transfer to tin disulfide, both in laboratory tests and when ...

By Christian Edwards, Katie Hunt and Ed Upright, CNN (CNN) — The 2023 Nobel Prize in chemistry has been awarded to a trio of scientists who worked to discover and develop quantum dots, used in ...
