Introduction to 880 nm LED Technology

880 nm LED stands for Light Emitting Diode that emits light at a wavelength of 880 nanometers. The deep red emission of these LEDs is a result of the energy bandgap of the semiconductor material used in their construction. Typically, 880 nm LEDs are made using materials like Aluminum Gallium Indium Phosphide (AlGaInP) or Aluminum Indium Gallium Phosphide (AlInGaP), which have the desired bandgap for emitting light at this specific wavelength.

The technology behind 880 nm LEDs involves the fabrication of a semiconductor structure that includes an active region where the light is emitted. This active region is sandwiched between a p-type and an n-type semiconductor layer, which allows for the injection of electrons and holes, leading to the recombination process and the emission of light. The efficiency and brightness of an 880 nm LED depend on various factors such as the quality of the semiconductor material, the design of the device structure, and the manufacturing process.
