dc.description.abstractEnThe effect of oxygen substitution for sulphur has been investigated in germanium and boron based glasses con-taining heavy metal oxides (Sb2O3). After heat treat-ment under H2S flow, the colour of the glass (powder and bulk) changes from colourless to yellowish indica-tive of anion exchange. The oxygen substitution for sul-phur has been confirmed by the presence of a new Raman band located at 340 cm-1 corresponding to a Ge–S and Sb–S bond vibration. The influence of the borate addition has been studied. XPS measurements have shown (i) the oxidation of Sb3+ to Sb5+ during the melting which increases with an increase of boron content and (ii) the reduction of Sb5+ to Sb3+ during the sulphination, resulting in the departure of more than one oxygen anion upon replacement by one sulphur and in the absence of weight gain. It has been clearly dem-onstrated that sulphination near the oxide glass tran-sition temperature can lead to the formation of oxysulphide glass materials.
