Fabrication and characterization of Lu2O3:Eu3+ nanopowders and X-ray films

▶ Lu2O3:Eu3+ scintillation films were prepared using micro- and nanocrystalline powders. ▶ Lu2O3:Eu3+ monodisperse nanospheres show the most intensive X-ray luminescence yield. ▶ Lu2O3:Eu3+/polymer ratio of 80/20 is optimal for better films X-ray luminescence. ▶ Urea-derived phosphor films demonstrate homogeneous distribution of luminescence intensity.
