Introduction to 270nm LED Industry

1. Definition and Characteristics of 270nm LED

270nm LED, also known as ultraviolet LED, refers to a type of light-emitting diode with a peak emission wavelength of 270nm. It belongs to the high-energy ultraviolet LED category, with strong energy and high photoelectric conversion efficiency. The 270nm LED is widely used in various fields such as optoelectronics, medical treatment, and environmental protection.

2. Working Principle of 270nm LED

The working principle of 270nm LED is based on the semiconductor materials with strong ultraviolet emission properties. When the forward bias voltage is applied to the semiconductor material, the electrons and holes are injected into the depletion layer, and the recombination of electrons and holes in the depletion layer generates ultraviolet light. The key to achieving 270nm emission is the selection of appropriate semiconductor materials and the optimization of the device structure.

3. Semiconductor Materials for 270nm LED

The semiconductor materials used in 270nm LED mainly include zinc selenide (ZnSe), zinc sulfide (ZnS), and gallium nitride (GaN). Among them, ZnSe has excellent optical properties and is widely used as the substrate material. ZnS and GaN are commonly used as the active layer material, which can emit strong ultraviolet light with a peak wavelength of 270nm.
