Yup, looks like “ The Ultraviolet spectrum has four wavelengths, (see illustration below), labeled: UV-A (400 to 315 nm); UV-B (315 to 280 nm); very high energy and destructive UV-C (280 to 200 nm); and Vacuum UV (200 to 100 nm). Only this last wavelength, Vacuum UV, is capable of producing ozone.” https://uvresources.com/the-ultraviolet-germicidal-irradiation-uv-c-wavelength/ https://uvresources.com/the-ultraviolet-germicidal-irradiati... Don’t know much about it though.
