Impact of samarium ion concentration on the physical, structural and optical properties of multi-component borate glasses

Abstract

The new glass system Borate-Sodium-Zirconium glasses activated with various concentration of samarium ion were successfully synthesized via melt quench method and their physical, structural and optical properties have been examined. The amorphous nature as well as various functional group that occur in the matrix are confirmed through XRD and FTIR measurements. All the physical parameters were calculated and contemplated to understand the impact of Sm2O3 concentration on host glass. The obtained optical bandgap from Tauc's plot has been utilized to calculate the refractive index and those were compared with standard formulae. Other optical parameters including numerical aperture, molar refractivity, electronic polarizability, oxide ion polarizability and optical basicity were determined. The metallization standard got less than one and the interaction parameter decreased with respect to increasing the Sm2O3 concentration. From the luminescence studies, 0.5 mol% of Sm3+ doped sample showed maximum intensity in the reddish-orange region. The colorimetric factors like orange/ red (O/R) intensity ratio, CIE coordinates and correlated color temperature (CCT) were also assessed. The results indicate that prepared BNSm glasses are suitable for visible lasers and orange-red luminescence devices.
