چکیده انگلیسی
The influence of co-dopant Na2O on the thermoluminescence (TL) properties and kinetic parameters of Cu2O doped Calcium Lithium borate glass (CLB:Cu) are comprehensively examined and studied in this paper. The glasses were prepared by melt quenching method upon adding various Na2O concentrations of 0.1% to 1â¯mol%, and irradiated with 60CO gamma-ray, 6â¯MeV electron and 6â¯MV X-ray photon. The glow curve exhibits a prominent peak (TM) at 188â¯Â°C. The TL intensity and sensitivity was enhanced by a factor of 2 and 1.7 respectively due to the incorporation of Na2O, and this was attributed to the creation of extra electron traps mediated by radiative recombination energy transfer. We achieved good linearity of the TL yield with dose low fading, excellent reproducibility and a promising effective atomic number (Zeff = 8.85), all of which are highly suitable for dosimetry. The effects of sunlight on the TL are also tested and investigated. These attractive features demonstrate that our dosimeter is useful in personal, environmental and medical radiation therapy application.
