Synthesis, structural, optical and solid state NMR study of lead bismuth titanate borosilicate glasses

Various compositions (0.0 <= x <= 1.0) in the glassy system 55[(PbxBi1-x)TiO3]-44(2SiO(2).B2O3] doped with one mol percent of graphene nanoplatlets (GNPs) have been synthesized using the conventional melt-quenching technique. X-ray diffraction (XRD) study revealed the formation of bulk and transparent lead bismuth titanate borosilicate glasses. Density and molar volume were determined using the liquid displacement method. Structural analyses were carried out in detail using different characterization techniques such as infrared spectroscopy, Raman spectroscopy, UV-vis spectroscopy and solid state nuclear magnetic resonance (SSNMR) spectroscopy. Si-29 and B-11-MAS-NMR-spectral analysis for five glass samples with different fraction of PbO reveal that as increases the content of PbO, the silicate and borate network become more polymerized.
