Abstract
In this work, the effect of ZnO co-dopant on the thermoluminescence (TL) properties of Cu2O-doped calcium lithium borate glass was studied while the fabricated samples were irradiated with various radiation sources, namely gamma ray, 6 MeV electron and 6 MeV X-ray. Results showed that the addition of ZnO has led to the enhanced TL intensity and sensitivity by a factor of 4 and 3, respectively. This can be of special interest in incidental dosimetry; a linear response was obtained with all the beams. The thermal fading property was reduced by a factor 3, while the minimum detectable dose of the new dosimeter was 2.28 μGy. It was concluded that this dosimeter can be useful for personal, environmental, and medical radiation therapy applications.
