Deep ultraviolet (DUV) LED is a type of light-emitting diode (LED) that emits light in the deep ultraviolet region of the electromagnetic spectrum, which ranges from 200 to 280 nanometers (nm). These LEDs have been gaining significant attention in various industries due to their unique properties and potential applications. This article aims to provide an overview of the DUV LED industry, including its technology, market trends, and future prospects.

Technology of Deep Ultraviolet LED

The technology behind DUV LEDs is quite complex and involves the manipulation of semiconductor materials. DUV LEDs are typically made from a combination of gallium nitride (GaN), aluminum nitride (AlN), and silicon carbide (SiC) materials. These materials have specific band gaps that allow them to emit light at specific wavelengths, including the deep ultraviolet region. The manufacturing process of DUV LEDs involves several key steps: 1. Material Growth: The first step is to grow the semiconductor materials on a substrate. This is typically done using techniques like metalorganic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE). 2. Device Fabrication: Once the semiconductor materials are grown, the next step is to fabricate the LED structure. This involves creating a p-n junction and adding a layer of aluminum to the surface to improve the extraction of photons. 3. Luminescence Testing: After the device is fabricated, it is tested for luminescence to ensure that it emits light in the desired deep ultraviolet region. 4. Packaging: Finally, the LED is packaged with a lens or reflector to enhance its light output and direct it in a specific direction.
