IR LED 880 nm, or Infrared Light Emitting Diode with a peak emission wavelength of 880 nanometers, has become a crucial component in a variety of industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the world of 880 nm IR LEDs, exploring their technology, market trends, and potential future developments.

Introduction to IR LED 880 nm

IR LED 880 nm emits infrared light at a specific wavelength, which is typically used for applications requiring long-range detection and communication. Unlike visible light, infrared light is not visible to the human eye, making it ideal for covert operations and secure data transmission. The 880 nm wavelength falls within the near-infrared spectrum, which is just beyond the red end of the visible spectrum.

Technology and Manufacturing Process

The technology behind IR LED 880 nm involves the use of semiconductor materials that emit infrared light when an electrical current is applied. The most common materials used for these LEDs are aluminum gallium arsenide (AlGaAs) and aluminum indium gallium phosphide (AlInGaP). The manufacturing process involves epitaxial growth of the semiconductor layers on a substrate, followed by the fabrication of the LED structure, which includes the p-n junction and the metal contact.

Epitaxial growth is a process where a thin layer of semiconductor material is deposited on a substrate to create a single crystal structure. This process is crucial for achieving the desired optical and electrical properties of the LED. After the epitaxial growth, the LED structure is then patterned and etched to form the p-n junction and the metal contact, which allows for the injection of electrical current and the emission of light.
