Revolutionizing UV Lighting: The Breakthroughs and Innovations of Deep Ultraviolet LED Technology

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) spectrum, which ranges from 200 to 280 nanometers (nm). This unique spectral range has sparked significant interest in various industries, including healthcare, semiconductor manufacturing, and environmental monitoring. This article provides an in-depth introduction to the DUV LED industry, covering its technology, applications, market trends, and future prospects.

Technology and Manufacturing Process

DUV LEDs are based on the principle of electroluminescence, where an electric current excites electrons in a semiconductor material, causing them to recombine and emit light. The key challenge in manufacturing DUV LEDs lies in the development of suitable semiconductor materials and the optimization of the epitaxial growth process. The most commonly used materials for DUV LEDs are gallium nitride (GaN), aluminum nitride (AlN), and zinc selenide (ZnSe).

The epitaxial growth process involves depositing thin layers of semiconductor materials on a substrate to create a p-n junction. This process is typically carried out using metalorganic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE) techniques. The quality of the epitaxial layers directly impacts the performance of the DUV LED, including its brightness, efficiency, and lifetime.
