  2. Quantum dot - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot

    In June 2006, QD Vision announced technical success in making a proof-of-concept quantum dot display and show a bright emission in the visible and near infrared region of the spectrum. A QD-LED integrated at a scanning microscopy tip was used to demonstrate fluorescence near-field scanning optical microscopy ( NSOM ) imaging.

  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 laser - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot_laser

    A quantum dot laser is a semiconductor laser that uses quantum dots as the active laser medium in its light emitting region. Due to the tight confinement of charge carriers in quantum dots, they exhibit an electronic structure similar to atoms. Lasers fabricated from such an active media exhibit device performance that is closer to gas lasers ...

    Sony has a large selection of TVs with two main panel types – LED and OLED – but its recent high-end models come in a new type of jargon called Quantum Dot OLED (QD-OLED), which is a fancy way ...

  6. Quantum dot solar cell - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot_solar_cell

    A quantum dot solar cell (QDSC) is a solar cell design that uses quantum dots as the captivating photovoltaic material. It attempts to replace bulk materials such as silicon, copper indium gallium selenide (CIGS) or cadmium telluride (CdTe). Quantum dots have bandgaps that are adjustable across a wide range of energy levels by changing their ...

  7. Cadmium-free quantum dot - Wikipedia

    en.wikipedia.org/wiki/Cadmium-free_quantum_dot

    Cadmium-free quantum dot. Quantum dots (QDs) are semiconductor nanoparticles with a size less than 10 nm. [ 1][ 2] [ 3] They exhibited size-dependent properties especially in the optical absorption and the photoluminescence (PL). Typically, the fluorescence emission peak of the QDs can be tuned by changing their diameters.

  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 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.
