Abstract: | Results are presented of measurements on the infrared and laser Raman spectra of some lead silicate glasses of general formula (PbO)x(SiO2)y.For the infrared spectra, the frequency dependence of the imaginary component of the complex dielectric constant was determined from a Kramers-Krönig analysis of the reflectance spectra of the glasses at normal incidence. Apparently the addition of small amounts of PbO to vitreous silica serves to modify the continuous three-dimensional silica network; whereas in those glasses with a high lead content, the influence of the cation, Pb2+, appears to lie between that of network former and network modifier. |
