Popis:	The short-range order structures in some ternary ZrF4-BaF2-based glasses doped with EuF3, AlF3 or NaF are studied by XAFS. The near-neighbour structures around Zr, Ba and Eu are determined and compared with that in binary ZrF4-BaF2 glasses. The structural parameters of near neighbours around Zr and Ba are slightly reduced on addition of NaF or AlF3. Also, it is observed that the intensities of the 'white lines' in the Ln and Lm absorption edges of Eu and Ba in these glasses are different from those in corresponding fluorides. The causes leading to these changes are discussed. Meanwhile the differences between the bonding behaviour of Eu-F and that of Ba-F in the glasses are also discussed.
