This study presents the advanced results of our prior study on LiZnBO3 (LZB) phosphor. The samples were produced using the high-temperature solid-state reaction (SSR) technique by incorporating optimizations in the synthesis parameters to enhance crystallinity. Additionally, Raman spectroscopy in conjunction with X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy were utilized to study the structural properties. The samples were subjected to radiation exposure with photon energy of 6 MV, ranging from 0.5 to 8 Gy. To get a complete glow peak within the range, the pre-heat temperature was changed along with the reader's TTP (time-temperature profile) configuration. Two thermoluminescence (TL) glow peaks were detected at around 155 °C and 240 °C for the entire photon energy range. The low-temperature prominent peak is beneficial for improving the TL reader's efficiency and lifespan. According to fading investigations, these glow peaks demonstrated notable stability over a prolonged period of 30 days. The new minimum detectable dose was anticipated to be 31.4 mGy on average. Moreover, the proposed material's reusability was examined, yielding promising findings. Afterward, a comparative study was performed in terms of linearity, sensitivity, glow peak position, and intensity between the conventional TLD-100 and LZB samples. The results indicate that the LZB exhibits outstanding features as an alternative material for low-doseradiation dosimetry.
