quantum dot

n.
1. A semiconductor nanostructure in which the excitons are constrained in all three spatial dimensions.
2. Any of various semiconductor nanocrystals that absorb white light and then reemit it a couple of nanoseconds later in a specific color, used as probes for tracking antibodies, viruses, proteins, or DNA in cells and organisms.

More than using it for enhanced display quality, Apple is also looking to use quantum dot technology to give its iPhones better camera performance.
Scanning quantum dot microscopy involves attaching a single organic molecule the quantum dot to the tip of an atomic force microscope.
"Optical gain with electrically excited quantum dots is now a reality," says Victor Klimov, head of the quantum dot team.
It uses a 400nm to 1,700nm broadband image sensor with colloidal quantum dot (CQD) thin film photodiodes fabricated monolithically on silicon readout wafers.
The light color of a standard LED depends on the bandgap of the semiconductor used, but the color of a QD photon depends both on the semiconductor and the size of the quantum dot. As shown in Figure 2, bigger dots emit longer wavelengths, close to red (620-750 nm); smaller dots emit shorter wavelengths, closer to the violet end (380-450 nm) of the spectrum.
The research study is titled " Precise Study on Quantum Dot Sensor Market Covering Trends, Market Share and Forecast to 2027 " which encloses important data about the production, consumption, revenue and market share, merged with information related to the market scope and product overview.
Quantum dot printed security marks are invisible under normal conditions and can be transparent, like spot varnish.
A team at Swansea University made the discovery while they were testing out a new method of producing a type of "nanoparticle" called quantum dots.
This decrease in the band gap is because of the increase in the size of the quantum dot. The sample S4 has band gap of ~1.6 eV, which is very close to 1.53 eV of bulk Pb5Sb8S17 [13,14].
