A study published in Nano Letters demonstrates the use of quantum dots to create metasurfaces, enabling two objects to exist in the same space. Pohang University of Science and Technology (POSTECH) ...

Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from laboratory experiments to commercial products.

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

The environmentally friendly synthesis of carbon quantum dots (CQDs) using natural precursors is garnering considerable interest. Nonetheless, questions may arise concerning the properties and ...

(Nanowerk Spotlight) Augmented-reality glasses and near-eye microdisplays need tightly packed light-emitting pixels. At that scale, a pattern can fail even when it looks correctly drawn. A narrow ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

Researchers developed a fast, accurate method using Bayesian inference to identify electron charge states in quantum dots for quantum computing applications. (Nanowerk News) A research team at Tohoku ...

Carbon dots are luminescent carbonaceous nanoparticles that can be endowed with chiral properties, making them particularly interesting for biomedical applications due to their low cytotoxicity and ...

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a ...
