摘要：

Different glass samples were prepared in the system 59[(PbxCa1 - x)O center dot TiO2]-40[2SiO(2 center dot)B(2)O(3)]-1Fe(2)O(3) (0 <= x <= 0.7) employing a rapid melt-quenching technique. The IR structural and optical properties were evaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and ultraviolet-visible (UV VIS) spectroscopy. The amorphous nature of the glass samples were confirmed using XRD and SEM analysis. The Archimedes principle was used to calculate the density of all glass samples. The density increased with decrease in CaO content and the trend of molar volume reciprocal to the density. The band gap energy of the prepared glass samples are in the range of 1.25-2.37 eV and decrease with an increase in the concentrations of PbO.
