UV C diode, or ultraviolet C diode, is a crucial component in the field of ultraviolet (UV) technology. It plays a vital role in various applications, including water purification, air purification, and surface disinfection. This article aims to provide an in-depth introduction to the UV C diode industry, covering its history, technology, applications, market trends, and future prospects.

History of UV C Diode Technology

The concept of using UV light for disinfection dates back to the early 20th century. However, it was not until the 1970s that the development of UV C diodes began to gain momentum. The first UV C diode was developed by Hitachi, Ltd. in Japan in 1976. Since then, the technology has undergone significant advancements, with numerous companies entering the market to offer innovative UV C diode solutions.

Technology of UV C Diode

UV C diodes are semiconductor devices that emit UV light at a wavelength of 200 to 280 nanometers (nm). The most commonly used material for UV C diodes is gallium nitride (GaN), which offers high efficiency, stability, and durability. The structure of a UV C diode typically consists of a p-n junction, with the n-type layer doped with silicon or aluminum to create a depletion region that emits UV light when forward biased. The key factors that determine the performance of a UV C diode include its emission wavelength, intensity, and lifetime. The emission wavelength is crucial for the desired application, as different wavelengths have varying effects on microorganisms. For instance, UV C light with a wavelength of 254 nm is highly effective in destroying DNA and RNA, rendering bacteria and viruses inactive.
