Abstract

Ar ion beam sputtering has been used to deposit fluoride glasses films up to a micron in thickness on silica and silicon substrates, Fluorozirconate films were found to be dark in colour, attributed to the presence of reduced chemical species. Fluoroaluminate films composed of fluorides less susceptible to reduction were clear and fluorescence from a layer doped with 2 wt% Er3+ is presented.
