Introduction to 270nm LED

The 270nm LED is a type of ultraviolet (UV) LED that emits light at a wavelength of 270 nanometers. Unlike traditional visible light LEDs, which operate at longer wavelengths, 270nm LEDs produce light that is invisible to the human eye. This unique property makes them highly valuable in specific applications where UV light is required.

Working Principle of 270nm LED

The 270nm LED operates based on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in 270nm LEDs is typically made of Gallium Nitride (GaN) or Aluminum Gallium Nitride (AlGaN), which has a wide bandgap, allowing it to emit UV light at the desired wavelength.
