  • Extended X-ray absorption fine structure study on Bi modified GeS bulk glasses

  • EXAFS measurements have been performed from the Ge K edge and Bi L-III edge on GeSBi glasses with 6, 8 and 16 Bi at. %, and on crystalline Bi2S3, As expected, Ge is found to be fourfold coordinated with S atoms. It is also found that Bi is only coordinated with S with a coordination number CN = 4. This result for the CN of Bi contradicts the conclusion of Elliot and Steel. On the basis of the obtained CN of Bi, it is possible to exclude the presence of Bi2S3 microcrystalline inclusions and to assert that these glasses are homogeneous at the microscopic level.
