“In the field of high-energy X-ray imaging, (Gd, Lu)2O3:Eu scintillation ceramics have shown promising applications. Researchers have prepared Eu0.1Gd0.6Lu1.3O3 nano-powders with pure phase and investigated the influence of pre-sintering temperature on the microstructure, optical and luminescence properties. The Eu0.1Gd0.6Lu1.3O3 ceramics pre-sintered at 1 625 ℃ for 2 h combined with HIP post-treatment show the highest in-line transmittance of 75.2% at 611 nm. The PL, PLE and XEL intensities of the HIP post-treated Eu0.1Gd0.6Lu1.3O3 ceramics show a trend of first ascending and then descending with the increase of pre-sintering temperature.”
