With the rapid development of technology, the 270nm LED has emerged as a cutting-edge lighting solution with significant potential in various applications. This article aims to provide an in-depth introduction to the 270nm LED industry, covering its background, technology, applications, and future prospects.

Background of 270nm LED

The 270nm LED, also known as vacuum ultraviolet (VUV) LED, belongs to the ultraviolet (UV) LED family. Compared with traditional UV LEDs, the 270nm LED has a shorter wavelength, which enables it to emit light at a deeper level of the UV spectrum. This unique characteristic makes it highly valuable in various fields, such as sterilization, water purification, and surface treatment. In recent years, the demand for 270nm LED has been on the rise due to its excellent performance in these applications. As the global market for UV LED technology continues to expand, the 270nm LED has become a hot topic in the industry.

Technology of 270nm LED

The 270nm LED is based on the principle of semiconductor electroluminescence. When a forward bias is applied to the LED, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. The emitted photons have a wavelength of 270nm, which falls within the VUV range. The key to producing a high-quality 270nm LED lies in the material selection and device structure. The most commonly used materials for 270nm LED are gallium nitride (GaN) and zinc selenide (ZnSe). These materials have a wide bandgap, which is essential for emitting UV light with a short wavelength. The device structure of a 270nm LED typically includes a p-n junction, a buffer layer, and an active region. The buffer layer serves to reduce the lattice mismatch between the p-n junction and the active region, while the active region is responsible for emitting UV light.
