Abstract

Undoped and dysprosium doped lithium borate glass system with empirical formula (70-x) B2O3-30 Li2O-(x) Dy2O3 (x=0.1, 0.3, 0.5, 0.7, 1.0mol%) were prepared using the melt-quenching technique. The dosimetric measurements were performed by irradiating the samples to 6MV photon beam using linear accelerator (LINAC) over a dose range of 0.5-5.0Gy. The glass series of dysprosium doped lithium borate glass produced the best thermoluminescence (TL) glow curve with the highest intensity peak from sample with 1.0mol% Dy2O3 concentration. Minimum detectable dose was detected at 2.24mGy, good linearity of regression coefficient, high reproducibility and high sensitivity compared to the undoped glass are from 1.0mol% dysprosium doped lithium borate glass. The results indicated that the series of dysprosium doped lithium glasses have a great potential to be considered as a thermoluminescence dosimetry (TLD).
