Since then, the market for UV Diode LED has been growing rapidly.

Technology of UV Diode LED

UV Diode LED is a semiconductor device that emits ultraviolet light when an electric current passes through it. The core component of UV Diode LED is a semiconductor crystal, which is typically made of gallium nitride (GaN), zinc sulfide (ZnS), or aluminum nitride (AlN). These materials have excellent optical and electrical properties, making them suitable for UV Diode LED applications. The structure of a typical UV Diode LED consists of several layers, including the active region, the p-type layer, the n-type layer, and the encapsulation layer. The active region is the region where the ultraviolet light is emitted. The p-type and n-type layers are used to create a pn junction, which allows the electric current to flow and generate ultraviolet light. The encapsulation layer protects the LED from external factors and enhances its light extraction efficiency.
