The first coordination sphere of neodymium in glasses of the germanium chalcogenide-gallium chalcogenide system is studied by analyzing the optical transmission spectra of 0.85GeCh2 · 0.15Ga2Ch3 glasses (where Ch = O, S, Se, or Te) doped with neodymium chalcogenide. It is shown that the spectral shift in absorption bands of neodymium is a linear function of the mean electronegativity of chalcogens involved in the glasses, which indicates the coincidence between the average composition of the first coordination sphere of neodymium ions and the composition of anionic subsystem in the glasses under investigation.
