Abstract
An antimicrobial device, such as a flashlight, lantern, or lamp, is discussed herein. The antimicrobial device produces light in the ultraviolet (UV) spectrum (i.e., 150-250 nm), including 200-230 nm. The antimicrobial device includes an electron source, an extractor, and a target material. The electron source provides the electrons of sufficient energy to cause a photon to be released, whether by a target or by the electron itself. The extractor extracts the electrons from the electron source. The target material is a component at which the electron is directed. The target material can release a photon having a desired wavelength or within a desired wavelength range or cause the electron to release a photon having a desired wavelength or within a desired wavelength range.
