Abstract

Silica nanoparticle coating on 250 to 1000 um flexible quartz optical fiber facilitates side-emission of germicidal ultraviolet light (UV-C), which shows promise for disinfection of contaminated air, water, and surfaces. This work aims to develop an understanding of light interactions with the silica nanoparticles to allow more uniform side-emission of germicidal light along longer lengths of optical fibers. Two forms of light energy (refracted light and evanescent waves) are transmitted through optical fibers.
