275 nm LED, or ultraviolet (UV) LED, is a cutting-edge technology that has gained significant attention in recent years. With its ability to emit light at a shorter wavelength, it has a wide range of applications in various industries, including medical, environmental, and industrial fields. This article aims to provide an in-depth introduction to the 275 nm LED industry, covering its technology, applications, market trends, and future prospects.

Technology of 275 nm LED

275 nm LED is a type of UV LED that emits light at a wavelength of 275 nanometers. The technology behind 275 nm LED is based on the principles of solid-state lighting. Unlike traditional UV lamps that use mercury vapor or other gases, 275 nm LED utilizes a semiconductor material, typically gallium nitride (GaN), to generate UV light.

The process of producing 275 nm LED involves growing a thin layer of GaN on a substrate, typically sapphire or silicon carbide (SiC). The GaN layer is then doped with other elements, such as indium or aluminum, to create a p-n junction. When an electric current is applied to the p-n junction, electrons and holes recombine, emitting UV light.

One of the key challenges in developing 275 nm LED technology is the high defect density in GaN materials. These defects can lead to reduced light output and efficiency. Researchers have been working on improving the quality of GaN materials and optimizing the device design to enhance the performance of 275 nm LED.
