Working Principles of 254 nm UV Light LED

The 254 nm UV Light LED operates on the principle of electroluminescence, which involves the excitation of electrons within a semiconductor material. When an electric current is applied, electrons are excited from the valence band to the conduction band, releasing energy in the form of photons. The emitted photons have a wavelength of 254 nm, which falls within the ultraviolet (UV) spectrum. The semiconductor material used in 254 nm UV Light LED is typically a combination of gallium nitride (GaN) and aluminum nitride (AlN), which are known for their high UV emission efficiency. The structure of the LED consists of a p-n junction, where the p-type and n-type regions are created by doping the semiconductor material with impurities. The electric field across the junction promotes the recombination of electrons and holes, leading to the emission of UV light.
