LED 260nm: A Breakthrough in UV LED Technology

Introduction to LED 260nm

LED 260nm refers to a type of ultraviolet (UV) light-emitting diode (LED) that emits light at a wavelength of 260 nanometers. This innovative technology has been a significant breakthrough in the field of UV LED applications, offering numerous advantages over traditional UV sources. In this article, we will explore the various aspects of LED 260nm, including its working principle, applications, and future prospects.

Working Principle of LED 260nm

LEDs are semiconductor devices that emit light when an electric current passes through them. The working principle of LED 260nm is based on the same principle, but with a crucial difference: the material used to create the LED. LED 260nm is typically made of gallium nitride (GaN) or aluminum gallium nitride (AlGaN) as the active layer, which emits UV light when excited by an electric current. The key to achieving a 260nm wavelength lies in the composition and structure of the LED. The GaN or AlGaN material is doped with certain impurities to create a p-n junction, which generates UV light when electrons recombine with holes. The 260nm wavelength corresponds to the bandgap energy of the material, which determines the energy of the emitted photons.
