| 英文摘要 | After a post-annealing treatment, spark-plasma-sintered (SPSed) black lutetium titanate (Lu2Ti2O7 ) became colorless and the transmittance at 550 nm increased from zero to 57%. To investigate the effect of post-annealing, transmission electron microscopy, X-ray photoelectron spectroscopy, and impedance spectroscopy were performed on the SPSed Lu2Ti2O7 body before and after annealing. Clean grain boundaries and triple junctions with high crystallinity were observed in both samples. X-ray photoelectron spectra revealed that both carbon contamination and lattice defects existed in the sample before annealing. The post-annealing process could help to eliminate the carbon contamination and compensate for defects. The Lu2Ti2O7 body exhibited higher bulk conductivity at relatively low temperatures before annealing than that after annealing and the possible cause was analyzed. |
