Induced thermoluminescence of X-ray irradiated nanostructured zinc oxide

We report an in situ analysis of thermally stimulated luminescence (thermoluminescence, TL) of a sol–gel derived nanostructured ZnO. The quenching of thermoluminescence with Fe-doping in ZnO has also been investigated. A prominent emission spectra emerging around 600 nm at 180 °C in a bare-ZnO has been attributed to the high fraction availability of doubly ionized oxygen vacancies (O2−) in these novel materials.
