Today, 275 nm UV LEDs are widely used in various industries, thanks to their unique properties and applications.

Technology of 275 nm LED

275 nm UV LEDs are based on the principle of electroluminescence, where an electrical current excites electrons in a semiconductor material, causing them to recombine and emit UV light. The key to producing 275 nm UV LEDs lies in the choice of semiconductor materials and the design of the LED structure.

The most commonly used semiconductor material for 275 nm UV LEDs is gallium nitride (GaN), which offers a wide bandgap and high electron mobility. To achieve the desired emission wavelength, the GaN crystal structure must be carefully engineered to introduce strain and control the energy levels of the electrons. This process is known as quantum confinement.

In addition to GaN, other materials such as aluminum gallium nitride (AlGaN) and zinc selenide (ZnSe) are also used to produce 275 nm UV LEDs. The LED structure typically consists of a p-n junction, where the p-type layer is doped with acceptor atoms to create holes, and the n-type layer is doped with donor atoms to create electrons. When an electrical current is applied, electrons and holes recombine at the junction, emitting UV light.
