Abstract
In this work, the thermoluminescence (TL) dosimetric characteristics of xLi2O (100−x) P2O5 glass system, with (x=50, 60, 70) have been studied. The glass samples were prepared by using a conventional melt-quenching method and checked using X-ray diffraction (XRD) pattern and scanning electron microscope (SEM). It was shown that the sample [50P2O5–50Li2O] leads to the generation of thermoluminescence signals upon irradiation and it has the highest TL response where the effect of nano-particles to improve of TL response of 50P2O5 50Li2O was clear. It has one glow peak around 150–250°C shifted to higher temperature with dose increases and TL peak becomes wider and smaller as dose decreases. Linear dose response is observed up to 200Gy. 50P2O5 50Li2O glass, to become a good dosimetry it needs to add the appropriate transitional metal (activator) to overcome the problem of high fading.
