UV C diode, also known as ultraviolet C diode, is a type of semiconductor diode that emits ultraviolet light at a wavelength of 200 to 280 nanometers. It has become increasingly popular in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to the UV C diode industry, covering its history, technology, applications, and future prospects.

History of UV C Diode

The concept of UV C diode was first proposed in the 1970s. However, due to technological limitations and high costs, it was not widely used until the 21st century. With the rapid development of semiconductor technology and the increasing demand for disinfection and sterilization in various fields, UV C diode has gained considerable attention and has been widely used in medical, water treatment, and air purification industries.

Technology of UV C Diode

UV C diodes are made of gallium nitride (GaN) or silicon carbide (SiC) semiconductor materials. The key technology of UV C diode is the epitaxial growth of the semiconductor layer, which determines the performance and stability of the diode. Currently, the mainstream epitaxial growth methods include metal-organic chemical vapor deposition (MOCVD) and hydride vapor phase epitaxy (HVPE). These technologies have made it possible to produce high-quality UV C diodes with high efficiency and long service life.
