History of UV LED Diodes

The concept of UV LED diodes dates back to the early 20th century when scientists discovered that semiconductors could emit light when an electric current was applied to them. However, it wasn’t until the late 1990s that the technology for producing UV LED diodes became commercially viable. The breakthrough came when Japanese researchers developed a method for growing gallium nitride (GaN) on sapphire substrates, which allowed for the production of UV LED diodes with high efficiency and stability.

Technology of UV LED Diodes

UV LED diodes are semiconductor devices that emit ultraviolet light when an electric current passes through them. The key components of a UV LED diode are the semiconductor material, the p-n junction, and the encapsulation material. The semiconductor material is typically gallium nitride (GaN), gallium phosphide (GaP), or zinc sulfide (ZnS), which emits UV light when excited by an electric current.

The p-n junction is formed by doping the semiconductor material with impurities to create an electric field that facilitates the emission of UV light. The encapsulation material is used to protect the semiconductor material from external factors such as moisture, dust, and mechanical stress. The encapsulation material also plays a crucial role in improving the light extraction efficiency of the UV LED diode.
