Abstract
In this work, the thermoluminescence (TL) properties of MgO co-doped with Al3+ and Li+ cations, prepared by microwave-assisted solution combustion synthesis, using glycine as a fuel, are presented for the very first time. The X-ray diffractometer pattern confirmed MgO:Al3+,Li+ cubic phase formation and showed minor presence of a secondary phase associated with Al3+ cations. The energy band gap of the sample was approximated to 3.52 eV using the Kubelka-Munk relation. TL spectroscopy equipped with a beta source for sample irradiation was used to investigate electron trapping centres of MgO:Al3+,Li+. The dose-response measurements confirmed the general order kinetics. The depth of these electron trapping centres was approximated to be from 0.70 to 0.81 eV.
