Basic Principles of 850nm Infrared LED

The 850nm infrared LED is a semiconductor device that emits infrared light when an electric current is applied. The basic principle of its operation is based on the photoelectric effect. When the electric current passes through the PN junction of the semiconductor material, electrons and holes are generated, and when they recombine, photons are emitted. The wavelength of the emitted light is determined by the energy band gap of the semiconductor material. In the case of 850nm infrared LED, the semiconductor material commonly used is aluminum gallium arsenide (AlGaAs), which has a relatively large energy band gap, emitting infrared light at a wavelength of 850 nanometers.
