Abstract

© 2017 Author(s).Radiographic imaging which transforms y or x rays into visible light is one of the most important developments in the field of digital imaging systems in recent years. Materials consisting of rare earth elements have strong scintillation properties in digital radiology. Gd2O2SO4 is studied due to having effective magnetic properties and excellent luminescence spectra. Additionally, Gd2O2SO4:Eu3+ has thermal stability and ideal red light emission performance with peak emission at around 618 nm when activated under X-ray or ultraviolet light. In this study, Gd2O2SO4:Eu3+ nanoparticles were synthesized by sol-gel method and were calcined at 950 °C in argon gas atmosphere. In the analysis of the produced nanoparticles XRD, SEM, XPS and optical luminescence devices were used to evaluate the results.
