    • Abstract

       

      Herein, we reported physical, optical and NMR characteristics of SrTiO$_3$-based borosilicate glasses-doped chromium trioxide, CrO$_3$ (1–7 mol%). Five glass samples (GS) were fabricated from the glassy system 60[Sr.TiO$_3$]–40[2SiO$_2$.B$_2$O$_3$] via a rapid melt-quench technique. X-ray diffraction analysis revealed the unstructured behaviour of the glasses. Numerous physical parameters were calculated and explained in detail. Urbach energy ($E_U$) and skin depth (${\delta}$) were studied to approve the disordered structure of glasses. Recorded infrared spectra of glasses were utilized to clarify the stretching mode of vibrations between the atoms, which correlated with their structural features and compositional variations. The energy bandgap ($E_g$) was estimated by employing a Davis and Mott relationship that comprises an absorption coefficient, ${\alpha}$, as well as photon energy, hv. Further, nuclear magnetic resonance (solid-state) spectra of the glasses were recorded and their analysis showed that the silicate and borate networks became highly polymerized with decreasing concentration of SrTiO$_3$.
