Among the different wavelengths of IR light, 950nm IR LED (Light Emitting Diode) has gained significant attention due to its unique properties and applications. This article aims to provide an in-depth introduction to the 950nm IR LED industry, covering its technology, applications, market trends, and future prospects.

Technology of 950nm IR LED

950nm IR LED is a type of semiconductor device that emits infrared light at a wavelength of 950nm. It is based on the principles of quantum mechanics and solid-state physics. The key components of a 950nm IR LED include a p-n junction, a semiconductor material, and an encapsulation material. The semiconductor material is typically gallium nitride (GaN) or aluminum gallium nitride (AlGaN), which can be doped with indium or zinc to achieve the desired emission wavelength.

The p-n junction is formed by combining a p-type semiconductor material with an n-type semiconductor material. When an electric current is applied to the junction, electrons and holes are generated, and recombination of these particles emits photons. The encapsulation material is used to protect the semiconductor material from external environmental factors, such as moisture and dust, and to enhance the light extraction efficiency.
