Excerpt from note:

Ultraviolet LEDs have many interesting applications. UVA/UVB/UVC LEDs can act as compact and affordable pump light sources for various spectroscopy applications in lifescience, materials science, medicine, environmental monitoring, and sensing. Additionally, UVA LEDs are used for UV curing (resins, adhesives etc.), lithography, 3D printing and more; UVB LEDs are used in skin treatment, tanning, and plant lighting to name a few applications. UVC LEDs are employed for ultraviolet germicidal irradiation (UVGI) in which the UVC emission is used to kill or inactivate pathogens for disinfection of laboratory equipment, air, water, and/or food. As such it can be an effective weapon in battling infectious diseases [1].

Compared to low-and mid-pressure mercury based UV lamps, LED systems are more flexible, compact, have a faster on-off time, can handle more on-off cycles, and are environmentally more friendly as they do not contain mercury. In this note we will focus on UVC LED materials.
