Absorption spectra of Ti 3+ were measured for silicate, borate, and phosphate glasses doped with 0.5 mol% Ti 2 O 3 .The absorption coefficient at the peak wavelength of the 2 T 2 → 2 E transition of Ti 3+ is used as a parameter showing the relative content of Ti 3+ ions in glass samples. The effect of glass composition on Ti 3+ /Ti 4+ redox was studied. For multicomponent glasses, a basicity parameter calculated from glass composition is proposed in terms of coulomb force between the cation and the oxygen ion. The value of the absorption coefficient depends on basicity in silicate and borate glasses; however, it is independent of composition in phosphate glasses.
