A compact, flat lamp comprising large arrays of microcavity plasmas, capable of efficiently generating far UV-C (222 nm) photons from the B-X transition of KrCl* excimer, has been developed. Microplasmas are non-equilibrium, low-temperature plasma sources with higher power loading in the individual microcavities, thereby enabling them to form KrCl* excimer molecules efficiently. The array of these individual microcavities devices also exhibits higher angular radiation distribution up to 180 degrees.
In this paper, a far UV-C microplasma lamp with a flat form factor will be discussed for its performance to prevent airborne transmission of the virus by continuous viral density reduction in an indoor space.
