UV light diodes, also known as ultraviolet light-emitting diodes, are a type of semiconductor device that emits ultraviolet light when an electric current is applied. As a key component in various industries, UV light diodes have been widely used in optoelectronics, medical equipment, environmental protection, and other fields. This article will introduce the industry of UV light diodes, including their working principle, application fields, market trends, and future development prospects.

Working Principle of UV Light Diodes

UV light diodes are made of semiconductor materials, usually gallium nitride (GaN), zinc sulfide (ZnS), or silicon carbide (SiC). When an electric current is applied to the diode, electrons and holes are injected into the semiconductor material. Due to the energy difference between the valence band and the conduction band, electrons and holes recombine, releasing energy in the form of ultraviolet light. The wavelength of the emitted light can be adjusted by adjusting the composition and structure of the semiconductor material.
