Far infrared (FIR) LED, or far infrared light-emitting diode, is a type of semiconductor device that emits infrared radiation at a wavelength longer than visible light but shorter than terahertz radiation. These LEDs have gained significant attention in various industries due to their unique properties and applications. This article provides an in-depth introduction to the far infrared LED industry, covering its technology, applications, market trends, and future prospects.
Technology of Far Infrared LEDs
Far infrared LEDs are based on the principle of semiconductor electroluminescence. When a forward bias is applied to the p-n junction of a semiconductor material, electrons and holes recombine, releasing energy in the form of photons. The semiconductor material used in FIR LEDs typically includes gallium arsenide (GaAs), gallium antimonide (GaSb), and indium antimonide (InSb), which have direct band gaps suitable for emitting far infrared radiation.
The manufacturing process of FIR LEDs involves several key steps. First, the semiconductor wafer is cleaned and etched to create the desired p-n junction structure. Then, the wafer is doped with impurities to control the electrical properties. After that, the wafer is annealed to remove any defects and improve the crystal quality. Finally, the wafer is diced into individual chips, which are then mounted onto substrates and encapsulated to protect the LED from external factors.
