Structural development of tellurite glasses with the addition of Li 2 O and Na 2 O has been studied using infrared, Raman, and X‐ray photoelectron spectroscopies. The increase in intensity of the peak at 755 cm −1 in the infrared spectra as compared to the peak at 620 cm −1 suggests the transformation of TeO 4 building units to TeO 3 pyramids with the addition of alkali oxide. Proposed structural change is further supported by the strong compositional dependence of the 755‐cm −1 peak in the Raman spectra as well as by the formation of a shoulder in the O 1 s peak of X‐ray photoelectron spectra. In contrast to alkali silicate glasses, formation of nonbridging oxygens with the addition of alkali oxide is not observed.
