Physical, optical, thermoanalytical, and radiation response study of Eu 2 O 3 -doped zinc fluoro-telluroborate glasses

In the present study, Eu 3+ -doped zinc fluoro-telluroborate transparent glasses were prepared by the conventional melt−quench technique. Their density and refractive index values were measured, and using these values, different physical parameters (number density, oxygen packing density, no. of bonds/vol, etc.) were calculated and analysed. The XRD pattern displayed a disordered atomic arrangement in the glass network. The EDS spectra proved the purity of the samples exhibiting only those elements used during the synthesis. The good solubility of Eu 3+ ions in zinc fluoro-telluroborate glasses was analysed through fine absorption peaks in the UV−Vis−NIR range. The absorption intensities increased in all samples up to 3.0 mol% of Eu 3+ -doping concentration. The stabilities of the samples, such as ∆ T ~ (144–156) °C and H r ~ 2.33–4.00, calculated using characteristic temperatures ( T g , T x , T c , T m ) from DSC studies exhibited their promising candidature in a high-temperature environment. The Eu7 (Eu 3+ with 3.0 mol%) glass confirmed better attenuation properties (LAC, Z eff , HVL, MFP) compared to other composition (0–2.5 mol%) glasses.
