dc.description.abstractSeveral attempts were made to fabricate zirconia (ZrO2) reinforced strontium titanate (SrTiO3) borosilicate glasses in the system (100-x�y)[SrTiO3]-x[2B2O3.SiO2]-y[ZrO2] (38 ? x ? 39, 0 ? y ? 4 by mole %) via a rapid melt-quenching method. To check the amorphous behaviour of the prepared glasses, XRD measurements were performed. Further, density of the bulk transparent glasses was evaluated by liquid-displacement method (Archimedes� principle) and found to be in the range of 2.6068�3.0720 gcm?3. To study the effect of ZrO2 doping on the fabricated glasses, various physical parameters such as oxygen molar volume (Omv), molar volume (Vm), oxygen packing density (OPD), ion-concentrations (N), etc. were determined. Further, to investigate the molecular structure, and bonding information, FTIR spectroscopy was performed. Additionally, to determine the various optical properties, the UV�visible spectroscopy was also performed, and with the help of Davis-Mott plots, increasing optical band gap energies were obtained in the range of 4.29�4.78�eV. Besides these parameters, an optical dielectric constant (?), and average refractive index (?) were determined which lies within the increasing range of 120.0374�207.3341 and 1.9269�2.0690 respectively. Moreover, to elaborate the structure of the fabricated glasses, 29Si and 11B MAS SSNMR spectra were recorded which shows the formation of silicate networks which became highly polymerized with increasing concentrations of ZrO2. � 2023, The Author(s), under exclusive licence to Springer Nature B.V.
