A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
Quantum dot display (QD-LED)/ Electroluminescent quantum dots (ELQD, QDLE, EL-QLED)/ AMQLED Samsung, Sony, NanoPhotonica, Nanosys: Many expect that quantum dot display technology can compete or even replace liquid crystal displays (LCDs) in near future, including the desktop and notebook computer spaces and televisions.
To generate white light best suited as an LCD backlight, parts of the light of a blue-emitting LED are transformed by quantum dots into small-bandwidth green and red light such that the combined white light allows a nearly ideal color gamut to be generated by the RGB color filters of the LCD panel. The quantum dots may be in a separate layer as ...

Individual quantum dots can be created from two-dimensional electron or hole gases present in remotely doped quantum wells or semiconductor heterostructures called lateral quantum dots. The sample surface is coated with a thin layer of resist and a lateral pattern is then defined in the resist by electron beam lithography .
Schematic of a basic SET and its internal electrical components. A single-electron transistor (SET) is a sensitive electronic device based on the Coulomb blockade effect. In this device the electrons flow through a tunnel junction between source/drain to a quantum dot (conductive island).
