LEDs UVC
Applications for ultraviolet (UV) LEDs include the treatment of water, optical data storage, communications, the detection of biological agents, and the curing of polymers. Wavelengths between 100 nm to 280 nm are referred to as the UVC portion of the UV spectrum.

The ideal wavelength for disinfection is between 260 and 270 nm, with longer wavelengths producing exponentially less germicidal efficiency. In comparison to conventional mercury lamps, UVC LEDs provide a number of advantages, including the absence of hazardous materials, instantaneous on/off switching without cycle restrictions, reduced heat consumption with focused heat extraction, and increased durability.

In the case of UVC LEDs, a greater aluminum mole percentage is necessary to generate short wavelength emission (260 nm to 270 nm for disinfection), which makes the growth and doping of the material challenging. Historically, sapphire was the most widely utilized substrate for the III-nitrides since bulk lattice-matched substrates were not easily accessible. A substantial lattice mismatch between sapphire and the high-Al-content AlGaN structure of UVC LEDs causes more non-radiative recombination (defects). The difference between the two technologies appears to be less pronounced in the UVB range and at longer wavelengths, where the lattice-mismatch with AlN is larger because higher concentrations of Ga are required. This effect seems to get worse at higher Al concentration, so sapphire-based UVC LEDs tend to drop in power at wavelengths shorter than 280 nm faster than AlN-based UVC LEDs.
