| Abstract: | The infrared absorption spectra of the vitreous TeO2-P2O5 and Bi2O3-TeO2-P2O5 systems are studied in the spectral region of 4000 to 200 cm–1. Absorption bands in this range are assigned. The midband wavenumber and the absorption intensity for the attributed bands are found to be strongly and systematically dependent on glass composition. Quantitative analysis was also attempted to justify our attribution of the observed bands. |
