Working Principle of IR LED Emitters

IR LED emitters work on the principle of the光电效应. When a current is applied to the semiconductor material, it emits infrared radiation. The semiconductor material used in IR LED emitters is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared radiation efficiently.

The emission of infrared radiation occurs when electrons in the conduction band recombine with holes in the valence band. This process releases energy in the form of photons, which are infrared in nature. The wavelength of the emitted infrared radiation depends on the composition and structure of the semiconductor material.
