What is a 265nm UV LED?

A 265nm UV LED, or ultraviolet light-emitting diode, is a semiconductor device that emits light at a wavelength of 265 nanometers. This falls within the UV-C range of the electromagnetic spectrum, which is known for its germicidal properties. Unlike traditional UV lamps that use mercury vapor or other chemicals to produce UV light, 265nm UV LEDs are solid-state devices that offer numerous advantages in terms of efficiency, size, and environmental impact.

How Does a 265nm UV LED Work?

The operation of a 265nm UV LED is based on the principle of electroluminescence. When an electric current is applied to the semiconductor material, electrons are excited and recombine with electron holes, releasing energy in the form of light. The specific wavelength of light emitted depends on the composition and structure of the semiconductor material. In the case of 265nm UV LEDs, the semiconductor material is designed to emit light at this specific wavelength.
