Thermoluminescence characteristics of aluminium oxide doped with carbon and titanium co-doped subjected to 6 and 10 MV photon irradiations
In this work, thermoluminescence (TL) characteristics of powder form of polycrystalline aluminium oxide doped with 0.2 atomic percentage (at%) carbon (Al2O3:C 0.2 at%) and co-doped with two different concentrations of titanium (0.1 and 0.2 at%) subjected to X-ray irradiations were studied. This study was conducted to determine the capability of Al2O3:C co-doped with titanium (Al2O3:C:Ti) for thermoluminescent dosimetry (TLD). Al2O3:C co-doped with 0.1 at% titanium sample exhibited the highest TL intensity centered at 184 °C and a lower TL peak at 254 °C. It has shown some good dosimetric properties and can be considered to be used as TLD.
