Zusammenfassung: | In this study, the polycrystalline samples of undoped and different amount of Ce-doped MgB(4)O(7) were firstly prepared by a melting point method in air conditions with high temperature and then their thermoluminescence properties were reported. The most effective amount of dopants on MgB(4)O(7) is found to be 1% Ce. The main dosimetric properties which are namely TL sensivity, fading, linearity and re-usability of 1 % Ce-doped MgB(4)O(7) were examined in detail. The trap parameters namely order of kinestics (b), activation energy (E) and frequency factor (s) associated with the glow peaks in beta irradiated undoped and Ce doped MgB(4)O(7) samples were also obtained by computer glow curve deconvolution (CGCD) method. |
