✦ Synopsis

The 'D,+'F,_, emission of Eu'+ in cordierite is reported. Fluorescence line-narrowed emission by the 5D0+'F0 transition was used to study local structure around the Eu 3+ ion in cordierite glass. It was found that the Eu )+ ion forms quasi-molecular complexes with the non-bridging oxygen, enabling the FLN data to be accounted for in terms of a single non-random distribution of crystal field strengths.
