Synthesis of MgSO4 nanoparticle doped with Cu by hydrothermal method and investigation of its thermoluminescence properties in gamma irradiation

In this research MgSO4:Cu nanoparticles was synthesized for the first time by hydrothermal method. The size of the synthesized nanoparticles calculated by scherrer equation was about 36 nm using XRD pattern that this result was in agreement with that’s of SEM analysis. Thermoluminescence properties of the MgSO4:Cu nanoparticles was investigated in gamma irradiation of 60Co source. Optimum amount of impurity of the best TL sensitivity was obtained in 0.3 mol%. Thermoluminescence glow curve was de-convolved by GO model. It was found this glow curve has three overlapping peaks in 409, 440 and 529 K. Other TL factors such as reusability, linearity and fading were also studied.
