This article provides an in-depth introduction to the world of infrared 850nm LEDs, covering their history, technology, applications, and future prospects.

History of Infrared 850nm LEDs

The development of infrared 850nm LEDs dates back to the early 1970s when researchers at General Electric and Bell Telephone Laboratories began exploring the use of gallium arsenide (GaAs) as a semiconductor material for infrared light emission. In the late 1970s, the first practical infrared 850nm LEDs were developed, and they quickly found applications in consumer electronics, such as remote controls for televisions and audio equipment.

Since then, the technology has evolved significantly, with improvements in material quality, device efficiency, and manufacturing processes. Today, infrared 850nm LEDs are widely used in various industries, and the market for these devices is expected to grow significantly in the coming years.

Technology Behind Infrared 850nm LEDs

Infrared 850nm LEDs are made using a semiconductor material called gallium indium phosphide (GaInP), which is doped with gallium arsenide (GaAs). The GaInP material has a direct bandgap, which allows it to emit infrared light at a specific wavelength of 850nm when an electric current is applied.

The manufacturing process of infrared 850nm LEDs involves several steps, including epitaxial growth, doping, and packaging. Epitaxial growth involves depositing a thin layer of GaInP on a substrate material, such as silicon or sapphire, to create a single crystal structure. Doping involves introducing impurities into the GaInP material to alter its electrical properties. Finally, the LED is packaged to protect it from the environment and facilitate its integration into electronic devices.
