UVC diode, also known as ultraviolet C diode, is a type of semiconductor device that emits ultraviolet light with a wavelength of 200-280 nanometers. As a crucial component in various applications, UVC diodes have been widely used in the field of disinfection and sterilization. This article will provide an in-depth introduction to the industry of UVC diodes, covering their working principles, applications, market trends, and future development prospects.

Working Principles of UVC Diodes

UVC diodes are based on the principle of photoelectric effect. When the forward voltage is applied to the diode, electrons and holes are generated in the semiconductor material, and when these carriers recombine, ultraviolet light is emitted. The key to UVC diode performance lies in the semiconductor material, typically made of gallium nitride (GaN), silicon carbide (SiC), or aluminum nitride (AlN). These materials have excellent photoelectric properties and can efficiently convert electrical energy into ultraviolet light.
