Influence of morphology and chemical processes on thermoluminescence response of irradiated nanostructured hydroxyapatite

Abstract In this research work, hydroxyapatite samples were synthesized using hydrothermal method in laboratory through different chemical processes to produce powder material having different morphology. The crystal structure was carried out by X-ray powder diffraction data and the Rietveld method using MAUD software. Then the thermoluminescence responses of the samples with different morphologies were investigated from dosimetry point of view. The results were evaluated via different dosimetry aspects including dose-response, linearity and response fading, and the morphological effects were studied. The kinetic parameters of the thermoluminescence glow curves were also determined and compared using the Tm-Tstop method and the Tlanal software. The results showed that the changes in the synthesis conditions can significantly affect the produced particle morphology and the thermoluminescence response of hydroxyapatite samples, consequently.
