UV C diode, short for ultraviolet C diode, is a type of semiconductor diode that emits ultraviolet light at a wavelength of 100-280 nm. It is widely used in various fields such as water purification, air purification, sterilization, and food preservation. This article will introduce the industry of UV C diodes, including their working principle, application fields, market trends, and future development prospects.

Working Principle of UV C Diode

UV C diodes are based on the principle of semiconductor physics. When a forward voltage is applied to the diode, electrons and holes are separated, and the recombination of electrons and holes generates ultraviolet light. The core material of UV C diode is typically gallium nitride (GaN) or zinc selenide (ZnSe), which has excellent optical and electrical properties. The specific working principle is as follows:

1. When the forward voltage is applied, electrons and holes are separated in the p-n junction of the diode.
2. During the recombination process, the energy of electrons and holes is released in the form of ultraviolet light.
3. The ultraviolet light is emitted from the diode's surface and can be used in various applications.

Application Fields of UV C Diode

UV C diodes have a wide range of applications due to their strong sterilization and purification effects. The main application fields include:

1. Water Purification: UV C diodes can effectively kill bacteria, viruses, and other pathogens in water, ensuring the safety of drinking water.
