The difference is the size of the particles. Quantum dots, suspended in liquid, absorb white light and then reemit it in a specific color that depends on the particle's size. Each quantum dot is ...

Quantum dots are crystals of a fluorescent semiconductor material with a diameter of as few as 10 to 100 atoms (2-10 nm). They are used as labels for imaging molecules because of their very narrow ...

Being able to precisely manipulate interacting spins in quantum systems is of key importance for the development of reliable ...

Colloidal quantum dots are often referred to as artificial atoms, primarily because of their atom-like electron energy spectrum. Like atoms, they can form ordered structures that are commonly ...

A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light ...

A new technique for growing quantum dots has not only found a new, more efficient way to build a useful type of quantum dot, but also opened up a whole group of novel chemical materials for future ...

With the successful development of this heavy-metal-free quantum dot-based photodetector, the researchers went further. They teamed up with Qurv, an ICFO spin-off, to demonstrate its potential by ...

Quantum effects arise when particles shrink. As the size of a material is reduced to the nanoscale, the electronic and optical properties become dependent on the size and shape of the nanostructure.

By addressing the issue of quantum dot surface distortions that reduce solar cell performance, they successfully created ...

Nov. 6, 2024 — Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases.

Bottom image: Experimental traces of emission intensity from a conventional quantum dot (upper panel) and a novel asymmetrically compressed quantum dot (lower panel) resolved spectrally and ...

Quantum dots are nanoscale man-made crystals that have the ability to convert a spectrum of light into different colors. Each dot emits a different color depending on its size. (Image: RNGS ...
