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.
采用纳米粉末制备了Ce3+:(Lu0.7Y0.25La0.05)2O3透明陶瓷，并在氢气气氛中烧结。研究了Ce3+:(Lu0.7Y0.25La0.05)2O3透明陶瓷的光谱特性，发现了Ce3+在Lu2O3、Y2O3和La2O3固溶体中的发光现象。该陶瓷具有8.10 g/cm³的高密度以及7.15 ns和26.92 ns的短荧光寿命。有望成为一种良好的快速响应高温无机闪烁材料。
