WebMay 1, 2011 · Gd2O2S:Tb scintillators are often used in X-ray imaging but have been used only recently in neutron radiography [1–3]. Gd2O2S:Tb has a much higher neutron-capture cross-section than ZnS/LiF, which implies that the quantum efficiency for the conversion of neutrons to charged particles is much higher in the case of Gd2O2S:Tb than in the case … WebEu3+ and Tb3+ ions singly activated Gd2O2S hollow spheres have been successfully synthesized via solvothermal method by using Gd (NO3)3, Eu (NO3)3, Tb (NO3)3 and thiourea as raw materials. Detailed characterization of the as-prepared samples were obtained by X-ray diffractometry (XRD), field emission scanning electron microscopy (FE …
