Uv light diode, also known as ultraviolet light diode, is a semiconductor device that emits ultraviolet light. With the rapid development of technology, the application of UV light diodes has become increasingly widespread in various fields, such as medical treatment, environmental protection, and industrial production. This article will introduce the industry of UV light diodes, including their basic principles, types, applications, and market prospects.

Basic Principles of UV Light Diodes

UV light diodes are based on the photoelectric effect of semiconductors. When the forward voltage is applied to the diode, electrons and holes are generated in the semiconductor material, and when they recombine, ultraviolet light is emitted. The basic structure of a UV light diode includes a p-n junction, an anode, a cathode, and a semiconductor material. The most commonly used semiconductor materials are gallium nitride (GaN), silicon carbide (SiC), and zinc sulfide (ZnS), among others.

Types of UV Light Diodes

According to the wavelength range of the emitted light, UV light diodes can be divided into three types: short-wave UV light diodes, medium-wave UV light diodes, and long-wave UV light diodes. Short-wave UV light diodes have a wavelength range of 200-280nm, medium-wave UV light diodes have a wavelength range of 280-400nm, and long-wave UV light diodes have a wavelength range of 400-1000nm. According to the application field, UV light diodes can be divided into medical UV light diodes, environmental protection UV light diodes, and industrial UV light diodes.
