LED 950nm, also known as near-infrared (NIR) LED, has gained significant attention in recent years due to its unique properties and potential applications. This article aims to provide an in-depth introduction to the industry of LED 950nm, covering its technology, advantages, applications, and future prospects.

Introduction to LED 950nm

LED 950nm refers to a type of light-emitting diode that emits light at a wavelength of 950nm. This falls within the near-infrared spectrum, which is invisible to the human eye. Compared to other NIR LEDs, 950nm LEDs have several distinct advantages, such as longer wavelength, lower cost, and better performance in terms of light intensity and stability.

Technology of LED 950nm

The technology behind LED 950nm involves the use of gallium nitride (GaN) as the active material. GaN is a III-Nitride semiconductor material, which is known for its excellent electrical and optical properties. In the production process, GaN is doped with indium (In) to form InGaN, which serves as the light-emitting layer. The InGaN layer is then sandwiched between two p-type and n-type layers to form a p-n junction, which generates light when an electric current is applied. The key factors affecting the performance of LED 950nm include the quality of the GaN crystal, the structure of the p-n junction, and the encapsulation material. High-quality GaN crystals with a low defect density can significantly improve the light output of the LED. The p-n junction structure should be optimized to maximize the carrier injection and recombination efficiency. Additionally, the encapsulation material plays a crucial role in protecting the LED from environmental factors and improving its thermal dissipation.
