| Structural Analysis And Shielding Parameters Of NaSrB : Eu3+ Glass System Supreet Pal Singh1; Dinesh Kumar1; 1PUNJABI UNIVERSITY PATIALA, Patiala, India; PAPER: 258/Physics/Regular (Oral) SCHEDULED: 16:20/Mon. 28 Nov. 2022/Arcadia 3 ABSTRACT: Eu3+ doped borate glass matrix was prepared by conventional melt quenching technique. For this glass system some physical parameters such as Density (ρ), Molar volume (Vm), Oxygen packing density (O), Ion concentration (N), polaron radius rp(Å) have been calculated and their variation with rare-earth is studied. To check the radiation shielding ability of the prepared glass system, shielding parameters were calculated in the energy range 0.001 MeV to 0.5 MeV. The calculated parameters were analyzed on the basis of doping concentration and energy. The structure of the prepared glasses has been analyzed with the help of X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. The conversion of BO3 → BO4 and back conversion is observed and for more insight about the structure, the FT-IR spectrum has been deconvoluted. The band gap (Eg) was obtained with the help of Kubelka-Munk (K-M or F(R)) function. |
