Synthesis and luminescence characterization of cerium doped Lu2O3-Y2O3-La2O3 solid solution transparent ceramics.
Ce3+:(Lu0.7Y0.25La0.05)2O3 transparent ceramics were fabricated with nanopowders and sintered in H2 atmosphere. The spectral properties of Ce3+:(Lu0.7Y0.25La0.05)2O3 transparent ceramics were investigated and the luminescence of Ce3+ in the solid solution of Lu2O3, Y2O3 and La2O3 has been found. The ceramics has high density of 8.10 g/cm(3) and short fluorescence lifetimes of 7.15 ns and 26.92 ns. It is expected to be a good fast response high temperature inorganic scintillating materials.
