Synthesis of CaZrO3 nanostructured dosimeter with Eu3+ additive by sol-gel combustion method and study of its thermoluminescence properties

In this study, nanophosphorus Ca1-xZrO3:Eux (x=1,2,3,4,5 mol%) was prepared by sol-gel combustion method with citric acid as fuel at low temperature. The results of X-ray diffraction (XRD) analysis indicated the formation of sample phase at 350 °C with perovskite structure. XRD results also showed that the optimum temperature for the formation of single phase and crystalline nanophosphours sample of CaZrO3:Eu3+ is 700 °C. Surface morphology of the samples was identified by field emission electron microscopy (FE-SEM). X-ray energy dispersive analysis (EDAX) was employed to evaluate the elemental concentration of the samples. Study of thermoluminescence characterization of the produced samples were performed under constant UV irradiation with change of Europium impurity concentration and change of UV irradiation time for the sample Ca0.98Eu0.02ZrO3. Other thermoluminescence features such as reproducibility and fading were also evaluated for Ca0.98Eu0.02ZrO3 sample.
