Thermoluminescence and scintillation properties of Tb-doped lithium borate glass for tissue-equivalent dosimetry

초록

This study investigates the fabrication, characterization, and performance evaluation of Tb-doped Lithium borate glasses with varying compositions. The samples were synthesized by melt-quenching, forming non-crystalline networks with lithium concentrations up to 55 %. Optical characterization revealed emission peaks at 489, 545, 585, and 621 nm under X-ray and UV excitation, enabling precise measurement with photodetectors and spectrometers. The optimization of composition and further characterization of the material are discussed. The calculated Zeff values and thermoluminescence (TL) studies confirmed the suitability of LBO(Tb) glasses for dosimetry applications. These findings highlight the material's potential for real-time tissue equivalent and TLbased dosimetry technologies.
