La coordination N du cation Ag dans les verres Ag2 O - B2 O3 a été étudiée par EXAFS. On trouve N voisin de 2 et un facteur Debye-Walker qui suggèrent que l'ordre à courte distance des liaisons Ag-O est élevé. Ceci différencie les verres boratés des verres sodés. L'addition de Ag I ne modifie pas sensiblement la coordination Ag-O et la coordination Ag-I est voisine de 4.The coordination of the silver cation in the glasses Ag2 O n B2O3 has been studied by EXAFS. The values of coordination number (N≈2) and Debye-Waller factor denote an high degree of short range order in the bond Ag-O. This differentiates silver borate glasses from sodium borate glasses. When the glasses are doped with AgI, the Ag∼O coordination is found to remain substantial...
