Synthesis and thermoluminescence dosimetry properties of ZnGa2O4: Eu nanocrystals
Thermoluminescence and dosimetry characteristics of the Europium-doped zinc gallate (ZnGa2O4: Eu) nanocrystals synthesized via the sol–gel method have been experimentally studied. At the glow curve of ZnGa2O4: Eu, the prominent TL peak is observed at 210 °C, which is helpful for dosimetry applications. Investigating the effect of the amount of Eu on the dosimetry properties shows that the TL glow peaks’ maximum intensity is obtained with a 2 mol% concentration of Eu, whose sensitivity is 2.4 times higher than undoped ZnGa2O4 samples. Further, with gamma irradiation in a wide range of doses from 300 to 12 kGy using a 60Co gamma source, the linear dose response is observed up to 5 kGy in the Eu-doped zinc gallate samples. Other features, such as fading and reproducibility of the TL dose response, are also investigated. Considering the good results of this research, ZnGa2O4: Eu nano phosphor is suggested for high-dose gamma dosimetry applications.
