Working Principle of Black IR LED

Black IR LED is a semiconductor device that emits infrared light when an electric current is applied. It consists of a p-n junction, which is formed by doping the semiconductor material with impurities. When the p-n junction is forward biased, electrons and holes are injected into the junction region, where they recombine and release energy in the form of infrared light. The color of the infrared light is determined by the energy band gap of the semiconductor material.
