| Riassunto: | Title screen This study reports the synthesis and detailed characterization of Tb3+ doped sodium aluminum calcium borate (TbACNB) glasses, developed via melt-quenching, with the aim of establishing reliable luminescent calibration standards and X-ray imaging scintillators. A systematic investigation of photoluminescence, radioluminescence, proton-induced luminescence, and cathodoluminescence confirms a dominant and stable green emission centered at 546 nm, corresponding to the 5D4→7F5 transition of Tb3+ ions. Among all tested concentrations, the 6 mol% Tb2O3 doped glass exhibits the highest photoluminescence quantum yield of 25.67 %, optimal decay lifetime, and consistent emission peak positions across all excitation methods, indicating structural and spectral stability. Proton and X-ray irradiation studies demonstrate linear dose response behavior and high spatial resolution up to 10 lp/mm, validating the glass applicability for high-resolution X-ray imaging. The glass retains uniform luminescence and color stability, with CIE coordinates at (0.31, 0.60), confirming its potential as a fluorescence calibration reference. The novelty of this work lies in demonstrating multi-stimulus luminescence consistency, dose dependent response, and X-ray imaging, positioning 6TbACNB as a dual purpose material for optical calibration and X-ray imaging systems Текстовый файл AM_Agreement |
