摘要: X-ray photoelectron spectroscopy and Fourier transform-infrared studies were carried out on phosphate glasses containing oxides of iron, cobalt, nickel, copper zinc. The results suggest that the iron zinc may have structures in which both phosphorus (or zinc) atoms are tetrahedrally coordinated by oxygen into three-dimensional resemble polymorphic forms silica, whereas nickel consist polymeric chains PO4 tetrahedra bonded to adjacent via bridging oxygens. These polyphosphate linked together interaction between metal cation oxygens network former. In addition, core level 2p shake-up satellites 3d-transition ions these studied. support a suggestion glass most likely due electron transfer from ligand 3d orbitals.
