Thermoluminescence properties of KGdF4:Tb3+ polycrystalline materials
Keywords:
KGdF4:Tb3 , ThermoluminescenceAbstract
KGdF4 polycrystalline materials doped with Tb3+ ions (KGdF4:Tb3+) have been synthesized by the solid state reaction method at a temperature of 520 oC. Phase structure of prepared materials has been analyzed by X-ray diffraction patterns. The thermoluminescence (TL) properties of the material have been studied through the TL glow curves. The shape dependence of the TL glow curves on the kind of irradiations as well as the neutron dose-response of KGdF4:Tb3+ have been discussed in detail. By comparing the obtained results of KGdF4:Tb3+ with those of TLD100 and TLD600 dosimeters, the application ability of KGdF4:Tb3+ material in detecting the radiation type as well as measuring neutron doses has been proposed.
