Infrared LED diodes 850nm are a type of semiconductor devices that emit infrared light at a wavelength of 850 nanometers. These diodes are widely used in various applications, including consumer electronics, automotive, medical, and industrial sectors. This article provides an in-depth introduction to the 850nm infrared LED diode industry, covering its technology, applications, market trends, and future prospects.

Technology of Infrared LED Diodes 850nm

Infrared LED diodes 850nm are made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) as the semiconductor material. These materials have excellent optical and electrical properties, making them suitable for infrared light emission. The structure of an infrared LED diode typically consists of a p-n junction, which is formed by doping the semiconductor material with impurities to create a p-type and an n-type region.

The p-n junction is encapsulated in a transparent or semi-transparent material to prevent the escape of emitted light. The forward bias voltage applied to the diode allows electrons and holes to recombine at the junction, releasing energy in the form of infrared light. The wavelength of the emitted light is determined by the energy bandgap of the semiconductor material, which is a function of the composition and thickness of the material.
