Abstract
EU3+ in fluorozirconate glasses and glass-ceramics has been studied by fluorescence line narrowing (FLN). In glasses, the excitation spectru m of the D-5(0) level shows an inhomogeneous electronic peak with a ph onon side band (PSB). The effect of the PSB in the narrowed emission s pectra is analyzed. By a comparison of the spectra of devitrified glas ses and data of EuZrF7 crystal, it has been possible to our knowledge for the first time to obtain, precise information about the coordinati on environment of the EU3+ ions in a glass matrix.
