With its ability to emit UV light at a specific wavelength, UV LED has become a preferred choice for various industries, including medical, industrial, and consumer sectors. This article aims to provide an in-depth introduction to the UV LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Ultraviolet LED Technology

The development of UV LED technology dates back to the 1960s when the first UV LED was created. However, it was not until the late 1990s that significant advancements were made, leading to the commercialization of UV LED products. The early UV LED devices were limited in terms of efficiency and output power, but continuous research and development efforts have led to significant improvements over the years.

Technology of Ultraviolet LED

UV LED technology involves the use of semiconductor materials that emit UV light when an electric current is applied. The most commonly used materials for UV LED chips include gallium nitride (GaN), zinc sulfide (ZnS), and silicon carbide (SiC). These materials have a wide bandgap, which allows them to emit UV light at different wavelengths, ranging from 200 to 400 nm. The manufacturing process of UV LED chips involves several steps, including epitaxy, wafer slicing, dicing, and packaging. Epitaxy is the process of growing thin layers of semiconductor materials on a substrate to create the LED structure. Wafer slicing involves cutting the epitaxial wafer into individual chips, while dicing further divides the chips into smaller, usable units. Finally, the chips are packaged using various techniques to enhance their performance and reliability.
