850nm infrared light emitting diode, also known as 850nm infrared LED, is a type of semiconductor device that emits infrared light at a wavelength of 850 nanometers. As an important component in the infrared optical communication field, 850nm infrared LED has been widely used in various applications, such as infrared remote control, optical communication, and biometric recognition. This article will introduce the basic principles, application fields, and market prospects of 850nm infrared LED in the industry.

Basic Principles of 850nm Infrared Light Emitting Diode

The 850nm infrared LED is a semiconductor device made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) as the main material. The structure of the LED mainly includes an active region, a p-type layer, and an n-type layer. When the LED is biased, electrons and holes are injected into the active region from the p-type and n-type layers, respectively. Due to the difference in energy levels between the valence band and the conduction band, the electrons and holes recombine, releasing energy in the form of infrared light.
