Abstract
The boro-silicate glasses have been doped with different concentration of Eu2O3 keeping constant CoO concentration (0.02 mol%) and synthesized in melt quench technique, these glasses are characterized through physical parameters, optical absorption, photo, and X-ray luminescence spectroscopy. The results showed that the optical characteristics of the samples are dependent on the Eu2O3 content rather than CoO content inside the glass. We observe tetrahedral dominance of Co2+ in the present glass system. The absorption spectra showed the three broad band of Co2+ ion at 4T1 g(F) → 2T1 g, 4A2 (4F) → 1T1 (4P), and 5T2 g → 5Eg respectively. Using optical absorption spectra, the crystal field parameter (10Dq), Racah parameter (B) were evaluated for all the concentration of Eu3+ doped glass. The phonon side band spectrum shows 1067.98 cm−1 for the present glass system. The integral scintillating efficiency have been studied and exhibited that the value show 8.78 % compared with commercial BGO scintillating crystal. Judd-Ofelt intensity parameters were investigated and used to compute the radiative properties of present glasses. These studies are useful for optimizing glass composition and could be useful for the optical display devices.
