Fabrication and optical characterizations of lead calcium titanate borosilicate glasses

Different glass samples were prepared in the system 59[(PbxCa1−x)O·TiO2]-40[2SiO2·B2O3]-1Fe2O3 (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 s...

Description
Summary:Different glass samples were prepared in the system 59[(PbxCa1−x)O·TiO2]-40[2SiO2·B2O3]-1Fe2O3 (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 1.25–2.37eV and decrease with an increase in the concentrations of PbO. •Glasses were prepared in the system 59[(PbxCa1−x)O·TiO2]-40[2SiO2·B2O3]-1Fe2O3 (0≤x≤0.7).•Replacement of CaO by PbO, the increasing density and decreasing molar volume.•Band gap values decrease with increasing concentration of PbO.
