چکیده انگلیسی
Polymer based scintillator composites have been produced by combining poly(vinylidene fluoride), PVDF, and Gd2O3:Eu3+ scintillator nanoparticles. Additionally, 2,5 dipheniloxazol (PPO) and (1,4-bis (2-(5-phenioxazolil))-benzol (POPOP) were introduced in the polymer matrix in order to improve visible light yield under x-ray irradiation. It is shown that addition of PPO and POPOP has no influence on the polymer structure, increases dielectric constant from â¼7 to â¼14, which is suitable for improving energy resolution, and increases in 40% the overall transduction performance of the composite without sacrificing its homogeneity and transparency. Thus, the developed Gd2O3:Eu3+/PPO/POPOP/PVDF composites are appropriate for large area X-ray radiation detectors.
