Abstract
Ionic exchange has been carried out on vitreous fluoride materials : s ome fluoride ions have been replaced by hydroxyls by pyrohydrolysis of the fluoride glasses. The influence of the process parameters has bee n studied. The diffusion coefficients, concentration profiles and mola r extinction coefficients have been calculated. An increase of the ref ractive index of the hydrated layers, leading to the creation of optic al waveguides, has been systematically observed.
