Revolutionizing UV Technology: The Breakthrough of 265nm LED Innovation

LED 265nm, a cutting-edge technology in the field of optoelectronics, has been gaining significant attention in recent years. As the shortest wavelength of visible light, it offers numerous applications in various industries, from medical to industrial. This article aims to provide an in-depth introduction to the world of 265nm LED technology, covering its working principles, applications, advantages, challenges, and future prospects.

Introduction to LED 265nm

LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. The color of the emitted light depends on the energy bandgap of the semiconductor material used. In the case of 265nm LEDs, they are based on Gallium Nitride (GaN) and Aluminum Gallium Nitride (AlGaN) materials, which emit blue light with a very short wavelength.

Working Principles of LED 265nm

The working principle of 265nm LEDs is similar to that of other LEDs. When an electric current is applied to the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. The energy released determines the color of the emitted light. In the case of 265nm LEDs, the energy released is very high, resulting in a short wavelength and blue light.
