Deep ultraviolet (DUV) LEDs have emerged as a revolutionary technology in the field of lighting and optoelectronics. These LEDs emit light in the deep ultraviolet (DUV) range, which spans from 200 to 280 nanometers (nm). With their exceptional properties and wide range of applications, DUV LEDs are poised to transform various industries, including healthcare, environmental monitoring, and semiconductor manufacturing. This article provides an in-depth introduction to the DUV LED industry, covering its technology, applications, and future prospects.

Technology of Deep Ultraviolet LEDs

DUV LEDs are based on the principles of electroluminescence, where an electric current excites electrons in a semiconductor material, causing them to recombine and emit light. The key to generating DUV light lies in the choice of semiconductor material and the design of the LED structure. Here are some key aspects of DUV LED technology:

• Semiconductor Materials: The most commonly used semiconductor materials for DUV LEDs are zinc selenide (ZnSe), gallium nitride (GaN), and aluminum nitride (AlN). These materials have band gaps that correspond to the DUV range, allowing them to emit light in this region.
• LED Structure: The structure of a DUV LED typically consists of a p-n junction, where the p-type and n-type regions are formed by doping the semiconductor material. The p-n junction is surrounded by a buffer layer and a sapphire substrate, which helps to dissipate heat and improve the LED's performance.
• Photocatalysis: One of the most significant applications of DUV LEDs is in photocatalysis, where the DUV light excites catalysts to break down pollutants and contaminants. This process is highly efficient and has the potential to revolutionize water purification, air purification, and waste treatment.
