This article aims to provide an in-depth introduction to the 275 nm LED industry, covering its technological background, applications, market trends, and future prospects.

Introduction to 275 nm LED

The 275 nm LED, also known as a vacuum ultraviolet (VUV) LED, operates at a very short wavelength, far beyond the visible spectrum. It emits light in the vacuum ultraviolet range, which is typically used for various industrial and scientific applications. The key advantage of 275 nm LED is its ability to produce high-intensity, short-wavelength light that can penetrate materials and sterilize surfaces effectively.

Technological Background

The development of 275 nm LED technology is a significant breakthrough in the field of optoelectronics. Traditional UV LEDs operate at wavelengths between 365 nm and 400 nm, which are still within the visible spectrum. However, the 275 nm LED operates at a much shorter wavelength, making it suitable for applications that require deep UV radiation. The manufacturing process of 275 nm LED involves the use of advanced semiconductor materials and epitaxial growth techniques. Gallium nitride (GaN) is the most commonly used material for the LED chip due to its excellent electronic properties and ability to emit UV light. The epitaxial growth process involves depositing a thin layer of GaN on a substrate, followed by the fabrication of the LED structure.

Applications of 275 nm LED

The 275 nm LED finds applications in various fields, including: 1. Water Purification: The short-wavelength UV light emitted by 275 nm LED can effectively destroy harmful microorganisms, such as bacteria and viruses, in water. This makes it a valuable tool for water purification and sterilization in both industrial and household settings. 2. Surface Sterilization: The high-intensity UV light can penetrate materials and kill pathogens on surfaces, making it ideal for medical equipment sterilization, food processing, and laboratory environments. 3. Material Analysis: The deep UV radiation can be used for material analysis and surface inspection in semiconductor manufacturing and other high-tech industries. 4. Aerospace and Defense: The 275 nm LED can be used for detecting and destroying harmful substances in aerospace and defense applications. 5. Biotechnology: The LED's ability to induce photodynamic therapy in cells makes it a potential candidate for cancer treatment and other biotechnological applications.
