Silica glass doping is widely used in fibre optic technology. Fluorine, decreasing the silica refractive index is one of the widespread dodpants. Fluorine-doped silica is, therefore, a material for cladding optical fibres. Fluorine is introduced into silica during glass synthesis by different techniques, the most flexible and promising one being reduced-presure plasmachemical deposition. Despite the widespread practical implementations of silica fluorination, the mechanism of fluorine incorporation into the glass network is so far poorly understood. This paper reports on a model for silica fluorination for the case of reduced-pressure plasma chemical deposition.
