265nm LED technology has emerged as a groundbreaking innovation in the field of light-emitting diodes (LEDs). This ultra-violet (UV) LED operates at a very short wavelength, offering a wide range of applications across various industries. In this article, we will delve into the details of 265nm LED technology, its working principle, applications, advantages, and challenges faced by the industry.
Introduction to 265nm LED Technology
265nm LED technology refers to the use of light-emitting diodes that emit light at a wavelength of 265 nanometers. This falls within the UV-C range of the electromagnetic spectrum, which is known for its germicidal properties. The development of 265nm LED technology has been driven by the increasing demand for advanced lighting solutions and the need for effective disinfection methods in various sectors.
Working Principle of 265nm LED
The working principle of a 265nm LED is similar to that of other LEDs, but with a few key differences. In a typical LED, electrons and holes recombine at the junction between the p-type and n-type semiconductors, releasing energy in the form of light. However, in 265nm LEDs, the bandgap of the semiconductor material is much smaller, resulting in the emission of shorter wavelengths of light.
The semiconductor material used in 265nm LEDs is typically a gallium nitride (GaN) alloy, which has a wider bandgap than silicon or gallium arsenide (GaAs). This allows for the emission of UV-C light at 265nm. The device structure of a 265nm LED includes a p-type GaN layer, an n-type GaN layer, and a thin active layer composed of GaN or other suitable materials.
