Working Principle of IR Emitter Diodes

The working principle of IR emitter diodes is based on the photoelectric effect of semiconductor materials. When an electric current passes through the diode, electrons and holes are generated in the semiconductor material, and they recombine to release energy. Part of this energy is emitted in the form of infrared radiation. The intensity and frequency of the infrared radiation depend on the material, structure, and operating conditions of the diode.
