UV diodes, also known as ultraviolet diodes, are a type of semiconductor diode that emits ultraviolet light when an electric current passes through it. With the rapid development of technology, UV diodes have become an indispensable part of various industries, such as medical, environmental protection, and optical communication. This article will introduce the industry of UV diodes, including their working principle, types, applications, and market trends.

Working Principle of UV Diodes

UV diodes are based on the photoelectric effect. When the forward voltage is applied to the diode, electrons and holes are generated in the semiconductor material. As the electrons move to the conduction band, they collide with the lattice atoms, emitting photons with energy greater than the band gap. These photons are in the ultraviolet range, and the energy of the photons is directly proportional to the band gap of the semiconductor material.

Types of UV Diodes

According to the emission wavelength, UV diodes can be divided into three types: short-wavelength UV diodes, medium-wavelength UV diodes, and long-wavelength UV diodes. Short-wavelength UV diodes have a wavelength of 200-280nm, mainly used in medical and environmental protection fields. Medium-wavelength UV diodes have a wavelength of 280-400nm, mainly used in optical communication and display fields. Long-wavelength UV diodes have a wavelength of 400-1000nm, mainly used in industrial and agricultural fields.
