Ultra Violet LEDs

An ultraviolet (UV) LED is a type of light-emitting diode (LED) that emits light in the ultraviolet spectrum. UV LEDs are typically made from semiconductor materials such as gallium nitride (GaN) or aluminum nitride (AlN), and are designed to operate in the UV range of the electromagnetic spectrum (usually between 200 and 400 nanometers). UV LEDs are used in a variety of applications, including water purification, air purification, and sterilization. They are also used in forensic and forensic document examination, where they can help to reveal hidden or altered writing. UV LEDs are known for their high efficiency, long lifetime, and compact size.
