In this study, we will examine the Raman and Compton scattering theories to explain a mechanism of the blue light emitted by a UV germicidal lamp, whose average wavelength is between λ ≈ 260 nm and λ ≈ 360 nm. A germicidal lamp emits ultraviolet C light (UV-C), which has a wavelength between 100 nm and 280 nm. Man can typically see visible light with a wavelength between 380 nm and 780 nm, but cannot see UV light from a germicidal lamp. However, we can observe the blue light that emanates from a germicidal lamp (wavelength for blue from 465 nm to 482 nm and violet from 380 nm to 450 nm). There are various reasons why we can measure the blue light coming from a UV germicidal lamp. Because a germicidal UV lamp emits blue light, this study will focus on the scattering, particularly the Raman and Compton. We will make a suggestion for exploiting the scattering-induced redshifts for a tiny neutral particle around the atoms.
