    en.wikipedia.org/wiki/Light-emitting_diode_therapy

    LEDs produce wavelengths that span from UV-A (350 nm) to near-infrared (NIR) (1100 nm). [14] The wavelength of the LED light can target different tissues. Long wavelength lights such as NIR/dark red(600-1000 nm) can have better tissue penetration and can easily absorb cytochrome c oxidase (CCO) targets by PBMT.

  4. Light-emitting diode physics - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode_physics

    The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide, and others, with various trace doping elements, are used to produce different colors of light. Another type of LED uses a quantum dot which can have its properties and wavelength adjusted by its size. Light ...
