Preparation and Characterization of the Thermoluminescence Properties of Mg-doped ZnO

ZnO and Mg-doped ZnO nanoparticles were prepared by sol-gel method. X-ray diffraction studies of the sample confirm hexagonal phase. Crystallite size calculated using Scherer equation and found to be 48.5nm for undoped ZnO and 44.3nm for 1% Mg doped ZnO, 40.9nm for 2% Mg-doped ZnO and 38.7nm for 3% Mg-doped ZnO. Undoped sample exhibit unstructured low intense TL glow curve, whereas Mg doped samples exhibit will structured TL glow curves with a broad peak around 2800C to 3300C  depends on the UV energy. The TL response as a function of UV energy showed a linearity behavior over the range investigated, and 1% Mg-doped ZnO sample gives very good reproducibility compared with 2% and 3% Mg-doped ZnO samples
