Thermoluminescence properties of lithium borate glass subjected to 60CO gamma ray

Abstract

Glass samples with composition of xLi2CO3-(100-x) H3BO3, with 10 =x = 25 were prepared by melt-quenching technique. The amorphous structure, sample morphology and thermoluminescence (TL) properties of the prepared samples were determined using powder X-ray diffraction (XRD) spectrometer, field emission scanning electron microscope (FE-SEM) and TLD reader, respectively. The samples were irradiated to Co-60 gamma source. The FE-SEM results show that the morphology of the prepared samples was in homogenous and transmitted surface. Furthermore the amorphous phase was confirmed by XRDanalysis. It was also found that the composition of Li2CO3 and H3CO3 affected the TL response and the highest TL response was observed for the sample with composition 15 mol % Li2BO3 and 85 mol % of H3CO3 after being irradiated to 10 Gy gamma ray. The sensitivity of this sample was of about 138.306 nC g-1 Gy-1.
