Introduction to LED 265nm
LEDs, or Light Emitting Diodes, have revolutionized the lighting industry with their energy efficiency and long lifespan. The development of 265nm LED technology has opened new doors for applications that were previously unattainable due to the limitations of visible light LEDs. The 265nm wavelength falls within the ultraviolet (UV) spectrum, which is beyond the visible range of human eyes.
Origins and Development
The concept of UV LEDs was first introduced in the late 20th century. However, it was not until the early 2000s that significant breakthroughs were made in the development of 265nm LEDs. Researchers and engineers from various companies and academic institutions around the world collaborated to overcome the technical challenges associated with emitting light at such a short wavelength.
The primary challenge in producing 265nm LEDs was the difficulty in finding a suitable semiconductor material that could efficiently emit UV light. Silicon carbide (SiC) and gallium nitride (GaN) were identified as promising candidates, but they required substantial improvements in terms of crystal quality and defect management.
