Colloidal quantum dots (CQDs) are semiconducting crystals. They exist on a nanometer scale (ca. 2–12 nm) and are coated with ligand/surfactant molecules to avoid agglomeration. Due to their size, CQDs ...

Quantum dots are composed of semiconducting materials like cadmium selenide (CdSe) or indium arsenide (InAs) and can be synthesized through various methods. For instance, colloidal synthesis and ...

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 ...

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 ...

A Los Alamos National Laboratory team has overcome key challenges toward technologically viable high-intensity light emitters based on colloidal quantum dot technology, resulting in dual-function ...

Semiconductor nanoparticles typically consist of a crystalline core made from a semiconductor material, such as cadmium selenide (CdSe), cadmium sulfide (CdS), or indium phosphide (InP). The core is ...
