Light-emitting diode - Wikipedia

By selection of different semiconductor materials, single-color LEDs can be made that emit light in a narrow band of wavelengths from near-infrared through the visible spectrum and into the ultraviolet range. As the wavelengths become shorter, because of the larger band gap of these semiconductors, the operating voltage of the LED increases. Blue LEDs have an active region consisting of one or more InGaN quantum wellssandwiched between t…
