摘要
High-transparent Eu3+-doped yttrium lanthanum oxide ceramics were fabricated with nanopowders and the highest transmittance in the visible light wavelength region reaches 78%. The Eu3+-doped transparent ceramics exhibited a broad absorption band around 240 nm, a sharp red emission at 611 nm under X-ray excitation and the fluorescent decay time of 0.96 ms. It is expected to be a potential polycrystalline scintillation material for the applications in medical-imaging detectors.
