Technology of Infrared LED Diodes 850nm

Infrared LED diodes with a wavelength of 850nm are based on the principle of electroluminescence. When a forward voltage is applied to the diode, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. The emitted photons have a wavelength of 850nm, which falls within the near-infrared spectrum. The key components of an 850nm infrared LED diode include the semiconductor material, the p-n junction, and the encapsulation material.

The semiconductor material used in 850nm infrared LED diodes is typically gallium arsenide (GaAs) or gallium aluminum arsenide (GaAlAs). These materials have excellent optical and electrical properties, making them ideal for infrared emission. The p-n junction is formed by doping the semiconductor material with impurities to create a region with excess electrons (n-type) and holes (p-type). The encapsulation material is used to protect the diode from environmental factors and improve its thermal dissipation.
