  2. Quantum dot - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot

    Quantum dots are particularly promising for optical applications due to their high extinction coefficient [68] and ultrafast optical nonlinearities with potential applications for developing all-optical systems. [69]

  3. 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 ...

  4. Quantum dot single-photon source - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot_single-photon...

    A quantum dot single-photon source is based on a single quantum dot placed in an optical cavity. It is an on-demand single-photon source. A laser pulse can excite a pair of carriers known as an exciton in the quantum dot. The decay of a single exciton due to spontaneous emission leads to the emission of a single photon.

  5. 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 ...

  6. Integrated quantum photonics - Wikipedia

    en.wikipedia.org/wiki/Integrated_quantum_photonics

    Typically, optical ring resonators, and long waveguide sections provide increased nonlinear interaction for photon pair generation, though progress is also being made to integrate solid state systems single photon sources based on quantum dots, and nitrogen-vacancy centers with waveguide photonic circuits.

  7. Light-emitting diode physics - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode_physics

    Quantum dots (QD) are semiconductor nanocrystals with optical properties that let their emission color be tuned from the visible into the infrared spectrum. [29] [30] This allows quantum dot LEDs to create almost any color on the CIE diagram. This provides more color options and better color rendering than white LEDs since the emission spectrum ...

  8. 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 ...

  9. Quantum sensor - Wikipedia

    en.wikipedia.org/wiki/Quantum_sensor

    In photonics and quantum optics, photonic quantum sensing leverages entanglement, single photons and squeezed states to perform extremely precise measurements. Optical sensing makes use of continuously variable quantum systems such as different degrees of freedom of the electromagnetic field, vibrational modes of solids, and Bose–Einstein condensates. [5]
