摘 要：A facile approach to preparing well-dispersed nanocrystals of BaCeO3 was developed by a combination of solvothermal and an- nealing processes. The precursor consisted of amorphous BaCO3 and CeO2, and the conversion of the precursor to crystalline BaCeO3 nanocrystals occurred upon heat treatment at a relatively low temperature. The as-processed BaCeO3 had an orthorhombic structure and the average size of such crystals was approximately 80 nm. The obtained products were characterized by Fourier Transform Infrared （FT-IR）, X-Ray Diffraction （XRD）, Laser Raman Spectroscopy （LRS）, Scanning Electron Microscopy （SEM）, Energy Dispersive X-Ray Spectrome- try （EDS）, and Transmission Electron Microscopy （TEM）. This preparation process could also be used to synthesize doped barium cerate complex oxides BaCe0.95M0.05O3-δ （M=Y, Nd, Gd, and Sm）.
