摘要

The study reports enhanced thermoluminescence response of dysprosium-doped aluminium–lithium-zinc-borate glasses for dosimetry applications. The glasses were prepared following the melting quenching process. X-ray diffraction (XRD) analysis demonstrates the absence of sharp Bragg peaks, confirming the amorphous nature of the samples. The density of the glass samples decreases from 5.60 to 1.56 g/cm3, and the molar volume increases from 12 to 49.18 cm3/mol with an increase in dysprosium concentration. Consistent particle distribution and homogenous surface morphology were shown by field emission scanning electron microscopy (FESEM) examination, suggesting a stable glass matrix structure appropriate for dosimetric applications. Fading of 7%, 10%, and 11% after 20 days, 30 days, and 50 days. The effective atomic number of the samples increased from 7.10 to 9.97 eV with a significant increase in sensitivity of 38.1–88.8 (Gy/nC/g) with increased dysprosium. The transitions peak photoluminescence emission shows: 4F9/2 → 6H15/2, 4F9/2 → 6HJ/2, and 4F9/2 → 6H13/2 at concentrations of 1.5 mol%, 2.5 mol%, 3.4 mol%, and 4.8 mol% Dy3+ observed. The samples with dysprosium show good reproducibility. Trap depth characteristics, an optimal energy level, and stability, thus reinforcing the glasses’ suitability for radiation dosimetry applications.
