The structural environment of rare earth elements (REE) in synthetic silicate glasses of Na2Si2O5 composition has been characterized through extended X-ray absorption fine structure spectroscopy (EXAFS) at the respective rare-earth LIII-edges, in order to obtain oxidation state, coordination number and
► We determined the local structure around REE in sodium disilicate glasses.
► REE3 + ions have octahedral geometry consistent with the analogous crystalline oxides.
► REE show no clear clustering tendency in sodium disilicate glasses.
► The
