Abstract Optical absorption spectra of Ni2+ ions in (100 − x)(PbO · GeO2) · xR2O3 (R = As, Sb, Ga) glasses containing NiO and their IR absorption spectra were measured. The value of 10 Dq does not change with the addition of As2O3, Sb2O3 or Ga2O3. The value of Racahs B parameter was calculated from the absorption wave number of v3 and v1. It is suggested that the Coulomb interaction between the d electrons in the Ni2+ ions increases with increasing As2O3 or Sb2O3 content.
