| 英文摘要 | Lu2o3 powders with an average particle size of about 40nm were produced by a precipitation methed using lu (no3)(3) and nh4hco3 as starting materials. the precipitation precursor is amorphous and transforms into pure lu2o3 phase by calcining at 600 degrees c for 2h. the resultant lu2o3, al2o3 and ceo2 powders were mixed by ball milling, and then sintered into a fully transparent ce:luag ceramic body by vacuum sintering at 1760 degrees c for 10h and annealed at 1450 degrees c for 20h. the resultant transparent ceramic has a uniform microstructure with an average grain size of about 4 mu m. the polished ce:luag ceramic disk with 1.2mm thickness is highly transparent. the transmittance in the visible region reaches 56%, which is 72% of the theoretical value. the emission spectrum at 470 similar to 650nm with the double peak structure (517nm and 552nm) excited by x-ray is the characteristic spectrum of ce3+ due to the 5d-4f transition, is consistent with that of luag:ce single crystals, well coupled with the silicon photodiodes and satisfies the property requirements of a scintillator. ce:luag transparent ceramics is a promising scintillating material. |
