Introduction to 275 nm LED Industry

What is a 275 nm LED?

A 275 nm LED, or Light Emitting Diode, is a type of semiconductor device that emits light when an electric current is applied. Unlike traditional LEDs that emit light in the visible spectrum, a 275 nm LED emits light in the ultraviolet (UV) range. This unique characteristic makes 275 nm LEDs highly sought after in various applications, including scientific research, medical diagnostics, and environmental monitoring.

How does a 275 nm LED work?

The working principle of a 275 nm LED is similar to that of other LEDs. It consists of a semiconductor material, typically a gallium nitride (GaN) or aluminum gallium nitride (AlGaN) compound, sandwiched between two electrodes. When an electric current is applied, electrons and holes are injected into the semiconductor material. As these charge carriers recombine, they release energy in the form of light. In the case of 275 nm LEDs, the energy released corresponds to UV light.

Applications of 275 nm LEDs

The narrow emission spectrum of 275 nm LEDs makes them highly valuable in various applications. Some of the key applications include: 1.
