880 nm infrared LED, also known as the near-infrared LED, has become a significant player in the optoelectronics industry due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to the 880 nm infrared LED, covering its technology, applications, market trends, and future prospects.

Technology of 880 nm Infrared LED

The 880 nm infrared LED is a type of light-emitting diode that emits light at a wavelength of 880 nanometers, which falls within the near-infrared spectrum. The technology behind these LEDs involves the use of semiconductor materials that can efficiently convert electrical energy into light at this specific wavelength.

These LEDs are typically made using gallium nitride (GaN) or aluminum gallium nitride (AlGaN) as the active layer, which is sandwiched between p-type and n-type layers. The p-type layer is doped with trivalent atoms, such as indium or zinc, to create holes, while the n-type layer is doped with pentavalent atoms, such as arsenic or phosphorus, to create electrons. When an electric current is applied, electrons and holes recombine at the active layer, releasing energy in the form of light.

One of the key advantages of 880 nm infrared LEDs is their high efficiency, which can reach up to 70%. This high efficiency is due to the narrow emission spectrum of these LEDs, which allows for a more focused light output. Additionally, 880 nm infrared LEDs have a long lifespan, typically exceeding 50,000 hours, making them a reliable choice for various applications.
