These tiny diodes have since revolutionized the UV lighting industry, replacing traditional UV lamps in many applications.

One of the key factors that contributed to the rapid development of 5mm UV LEDs was the discovery of new materials and processes that could efficiently convert electrical energy into UV light. The use of gallium nitride (GaN) as a semiconductor material played a crucial role in this advancement, as it allowed for the production of LEDs with higher efficiency and longer lifespan.

Technology and Materials

The 5mm UV LED is a type of solid-state lighting device that emits UV light when an electric current passes through it. The core of the LED is a semiconductor chip, which is typically made of gallium nitride or a similar compound. The semiconductor material is then encapsulated in a transparent or translucent housing to protect it from environmental factors and to optimize the emission of UV light.

Several key materials and processes are involved in the production of 5mm UV LEDs. These include:

• Gallium Nitride (GaN): The semiconductor material that provides the foundation for the LED's ability to emit UV light.
• Metalorganic Chemical Vapor Deposition (MOCVD): The process used to deposit thin films of GaN onto a substrate, creating the LED's semiconductor layer.
• Passivation Layer: A layer applied to the surface of the semiconductor to reduce electrical leakage and improve device performance.
• Phosphor Coating: A material applied to the surface of the LED to convert the UV light into visible light, making it more useful for certain applications.
