Abstract
The objective of this work is to test an efficient material synthesis method, for the development of thermoluminescence (TL) material using yttrium aluminium garnet. The TL properties of undoped, Ce/Tb/Pr/Eu/Yb/Nd doped Y3Al5O12 (YAG) polycrystalline material, synthesized by combustion synthesis at low temperature, under ultra-violet (uv) and γ -rays irradiation is reported. The effect of controlled Si codoping is also inspected. The introduction of the doping ions induces changes in the trapping processes and the TL efficiency. The TL signal of Ce doped YAG samples indicates a high sensitivity to uv, γ-ray irradiation. It has been found that there is a prominent enhancement in TL glow peak with Si doping. Trapping parameters of uv irradiated YAG:Ce/Si were calculated from the TL data. The prepared ceramics have found potential application for uv and γ−ray radiation dosimetry purpose.
