Raman and infrared spectra of ternary P[2]O[5] -PbO-Bi[2]O[3] glasses

Vibrational infrared and Raman spectroscopy were employed to investigate the structural arrangement of some selected glasses from the ternary system P[2]O[5]-PbO-Bi[2]O[3]. The obtained spectra were analyzed in order to elucidate the role of each of the component oxides and justifying their specific roles in the glassy network. The densities of the prepared glass samples were measured and their molar volumes are calculated and the data are analyzed in relation to the compactness of the structure
