Working Principle of Infrared Emitter LED

Infrared emitter LED is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a p-n junction, which is formed by a p-type semiconductor and an n-type semiconductor. When the p-n junction is forward-biased, electrons from the n-type semiconductor combine with holes from the p-type semiconductor, releasing energy in the form of infrared light. The wavelength of the emitted light ranges from 780nm to 3μm, which falls within the infrared spectrum.
