Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made ...

Sony has a method. Sony's X900 and W900 lines Three of Sony's 2013 TVs will use quantum dots in their backlighting, in the guise of QD Vision's Color IQ tech (the 65X900, 55X900, and 55W900).

The quantum dots are either arranged in a tube—a "quantum rail"—adjacent to the LEDs or in a sheet of film atop the light-guide plate. Quantum dots have one job, and that is to emit one color.

Samsung has introduced its new QLED TV lineup in India, featuring Real Quantum Dot Technology for enhanced visuals and 100% ...

Quantum dots are also used in biological research, according to science writer Chris Woodford of Explain That Stuff. The tiny dots are used like light bulbs to color-code specific cells that need ...

A quantum dot contains a small finite number (of the order of 1-100) of conduction band electrons, valence band holes, or excitons, i.e., a finite number of elementary electric charges.

Currently quantum dot displays, like Samsung's QLEDs, use a thin layer of quantum dots in front of blue LEDs. The LEDs create, you guessed it, blue light.

The larger quantum dots — those closer to 10 nanometers — glow red when light is passed through them. Smaller ones, closer to 2 nanometers, glow green when light is passed through them.

A quantum dot (QD) is nothing more than a submicroscopic crystal of semiconductor material (a “nanocrystal”), generally on the order of 10 nanometers (nm) in diameter or smaller.

However, quantum dots are not only used as "dyes," they are also used in solar cells or as semiconductor devices, right up to computational building blocks, the qubits, of a quantum computer.

The 2023 Nobel Prize in chemistry has been awarded to a trio of scientists who worked to discover and develop quantum dots, used in LED lights and TV screens, as well as by surgeons when removing ...
