Structural studies of iron doped B₂O₃•0.7PbO•0.3Ag₂O glasses by FT-IR and Raman spectroscopies
Glasses from xFe₂O₃·(100-x)[3B₂O₃·0.7PbO·0.3Ag₂O] system, with 0 ≤ x ≤ 20 mol.%, were prepared and investigated by means of two complementary spectroscopic methods, FT-IR absorption and Raman scattering in order to obtain information concerning the network structure. Both FT-IR and Raman spectros...

| description |
Glasses from xFe₂O₃·(100-x)[3B₂O₃·0.7PbO·0.3Ag₂O] system, with
0 ≤ x ≤ 20 mol.%, were prepared and investigated by means of two complementary
spectroscopic methods, FT-IR absorption and Raman scattering in order to obtain
information concerning the network structure. Both FT-IR and Raman spectroscopic
techniques have revealed changes in the local structure of the glasses when the
composition is modified. The iron ions modifier role is pointed out by the shape of the
recorded spectra, changed with increasing the Fe₂O₃ content. The influence of a gradual
addition of the iron oxide on the local structure of silver lead borate based glasses has
been studied. The FT-IR data indicate the presence of the BO₃ and BO₄ structural units in
the glasses, the network structure being mainly built by: di-, tri-, tetra-, penta- and orthoborate
groups. The characteristic bands of the different structural groups evidenced in
these glasses were identified and quantitatively analyzed after increasing the Fe₂O₃
content. The Fe₂O₃ content dependence of Ar (A₄/A₃) ratio (where the values A₄ and A₃
reflect the relative amount of tetra-, respectively tri-coordinated boron atoms) was
studied. In addition, characteristic vibrational modes of bonds from iron, lead and silver
oxides were detected in the FT-IR spectra. Raman data is in accordance with the FT-IR
results and complete them. Using Raman scattering, we detected new structural groups as
pyro-, ditri- and dipenta-borate groups, indicating changes in the structure of our glasses
