  2. Quantum dot display - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot_display

    A quantum dot display is a display device that uses quantum dots (QD), semiconductor nanocrystals which can produce pure monochromatic [a] red, green, and blue light. Photo-emissive quantum dot particles are used in LCD backlights or display color filters. Quantum dots are excited by the blue light from the display panel to emit pure basic ...

  3. Quantum dot - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot

    Quantum dots are theoretically described as a point-like, or zero dimensional (0D) entity. Most of their properties depend on the dimensions, shape, and materials of which QDs are made. Generally, QDs present different thermodynamic properties from their bulk materials. One of these effects is melting-point depression.

  4. Silicon quantum dot - Wikipedia

    en.wikipedia.org/wiki/Silicon_quantum_dot

    Silicon quantum dot. Silicon quantum dots are metal-free biologically compatible quantum dots with photoluminescence emission maxima that are tunable through the visible to near-infrared spectral regions. These quantum dots have unique properties arising from their indirect band gap, including long-lived luminescent excited-states and large ...

    The prize-awarding academy said that their findings on quantum dots, which in size ratio have the same relationship to a football, as a football to the earth, had "added colour to nanotechnology ...

  6. Graphene quantum dot - Wikipedia

    en.wikipedia.org/wiki/Graphene_quantum_dot

    Graphene quantum dots (GQDs) consist of one or a few layers of graphene and are smaller than 100 nm in size. [3][1] They are chemically and physically stable, have a large surface to mass ratio and can be dispersed in water easily due to functional groups at the edges. [4][5] The fluorescence emission of GQDs can extend across a broad spectral ...

    Nanocrystalline material. Science portal. Technology portal. v. t. e. Carbon quantum dots also commonly called carbon nano dots or simply carbon dots (abbreviated as CQDs, C-dots or CDs) are carbon nanoparticles which are less than 10 nm in size and have some form of surface passivation.
