265nm UV LED: A Revolution in UV Lighting Technology

Introduction to 265nm UV LED

The 265nm UV LED, also known as the ultraviolet LED, has emerged as a groundbreaking technology in the field of UV lighting. This innovative light source emits light at a wavelength of 265 nanometers, which falls within the UV-C spectrum. UV-C light has been extensively studied for its germicidal properties and is increasingly being utilized in various industries for disinfection and sterilization purposes.

How 265nm UV LED Works

The 265nm UV LED operates by using a semiconductor material that emits UV-C light when an electric current is applied. This process is known as electroluminescence. The semiconductor material used in these LEDs is typically a combination of gallium nitride (GaN), aluminum nitride (AlN), or zinc selenide (ZnSe), which have the ability to emit UV-C light efficiently. The structure of a 265nm UV LED consists of a p-n junction, where the p-type material has an excess of holes, and the n-type material has an excess of electrons. When an electric current is applied, the electrons and holes recombine, releasing energy in the form of UV-C light. The efficiency of the LED is determined by the quality of the semiconductor material and the design of the LED structure.
