What is a quantum dot? Quantum dots are tiny crystals of semiconducting material. The crystals are so small – just a few nanometers wide – that their physical size actually confines the electrons in the material to the point that it changes their behaviour. This means that quantum phenomena determine the properties of these tiny crystals ...
Quantum dots are manufactured nanocrystals that consist of ultra-fine semiconductor materials. The purpose of a quantum dot is to produce different colours of light depending on the size of the particle at that very moment. A larger particle will skew towards appearing as a red colour and the smaller the particle the more blue it will appear.
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 ...

Quantum dots are emissive particles (somewhat like phosphors on a plasma TV). When the particles are hit with photons from an outside light source (in the case of an LCD TV application, a blue LED light), each dot emits the color of a specific bandwidth, which is determined by its size. Larger dots emit light that is skewed toward …
