950 nm LED, or Light Emitting Diode, has emerged as a revolutionary technology in the field of optoelectronics. This type of LED emits light at a longer wavelength, which has a significant impact on various applications, ranging from medical to industrial sectors. In this article, we will delve into the details of 950 nm LED technology, its working principle, applications, advantages, and future prospects.

Introduction to 950 nm LED

The 950 nm LED is a type of infrared LED that emits light at a wavelength of 950 nanometers. Unlike visible light LEDs, which emit light in the range of 400 to 700 nanometers, 950 nm LEDs are invisible to the human eye. However, their longer wavelength offers several advantages in specific applications. The development of 950 nm LED technology has been driven by the increasing demand for high-performance, energy-efficient, and cost-effective optoelectronic devices.

Working Principle of 950 nm LED

The working principle of a 950 nm LED is similar to that of other LEDs. It consists of a semiconductor material, typically gallium arsenide (GaAs), which emits light when an electric current passes through it. When the current flows through the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. The longer wavelength of 950 nm is achieved by using a specific composition of the semiconductor material, which affects the energy band gap and, consequently, the emitted light wavelength.
