Ligand Field Spectra in Metaphosphate Glasses
The ligand field absorption spectra in the ultraviolet, visible, and near-infrared regions of metaphosphate glasses containing the first-row (3d) transition elements, Ti, V, Cr, Mn, Fe, Co, Ni, and Cu, were compared with spectra for the same elements in aqueous orthophosphate solution. In general, the positions of the glass ligand field absorption bands correspond to those of the solution, indicating that the transition element species in glass is coordinated in a similar manner to that of the same element ion complexed in the aqueous solution. Furthermore, when an effort is made to keep the surroundings of the transition metal species similar in glass and in aqueous solution, as in the present work, the ligand field spectra do not differ greatly. Variations from these similarities are discussed.
