Investigation of the thermoluminescence properties Ti4+ doped MgO synthesized solid-state assisted solution combustion synthesis method
Abstract
In this study, undoped MgO and titanium (Ti4+) doped MgO ceramics were synthesized using the solid state-assisted solution combustion synthesis method. The structural characteristics were investigated using X-ray diffraction (XRD) and scanning electron microscope (SEM). TL curves of the MgO:Ti4+(0.1%wt) ceramic consist of three TL peaks located at 70, 250 and 290 oC with a heating rate of 2 oC/s after 1 Gy beta dose. Radioluminescence (RL) characteristic of the MgO:Ti4+(0.1%wt) ceramic was studied with excitations between 200 - 1000 nm. It was found to be the four emission bands the maximums located at 327 nm (~3.79 eV), 694 nm (~1.78 eV), 715 (~1.73 eV), and 745 (~1.66 eV). Some dosimetric characteristics such as TL curve, reusability, dose-response, of the ceramic were investigated using the thermoluminescence (TL) technique using beta radiation of 90Sr/90Y. Dose-response characteristics showed the integrated TL signals between 170-350 oC exhibited a linear up to 20 Gy. The experimental results showed that if it is developed of the MgO:Ti4+(0.1%wt) ceramic can be considered as a dosimetric material with suitable properties in personal and medical applications.
