The present work explores the characteristics of rare-earth ions-containing chlorofluoride glasses, in which the anion-coordination environments around rare-earth ions are changeable by the substitution of Cl for F. In this study, chlorofluoroaluminate and chlorofluorocadmate glasses with substitutions of Cl for F were developed, whose compositions are 40AlF_3・(20-x)BaF_2・xBaCl_2・20CaF_2・17YF_3・3EuF_3 in mol%(x=0, 3, 6, 9 and 12)and 50CdF_2・(20-x)BaF_2・xBaCl_2・30NaCl+0.1EuF_3 in molar ratio(x=0, 5, 10, 15 and 20), respectively. Changes in the anion coordination around cations with the Cl substitution were examined by molecular dynamics simulation and Eu^<3+> fluorescence spectroscopy. The experimental results revealed that the chlorofluoroaluminate glasses satisfy the present research object, while the chlorofluorocadmate glasses exert no effect on controlling the anion-coordination environments around rare-earth ions.
