Synthesis and Structural Properties of Lead Strontium Titanate Borosilicate Glasses with Addition of Chromium Trioxide and Graphene Nanoplatlets

Various lead strontium titanate borosilicate glass samples were prepared with addition of 1 mol % of chromium trioxide and graphene nanoplatelets by convention melt quench method. Their structural and optical behaviors were studied by infrared spectroscopy, ultraviolet–visible spectroscopy, and scanning electron microscopy. The infrared spectroscopic studies were carried in the wavenumber range of 400–4000 cm−1. The energy band gap of bulk transparent glass samples were found by Tauc plots of ultraviolet–visible spectra. Surface morphological studied was done by scanning electron microscopy. The density of these prepared lead strontium titanate borosilicate glass samples were calculated by “Archimedes principle” of liquid displacement method.
