The BaHfO3∶Ce ultra-fine particles were prepared by C2H5OH/H2O mixed solvolthermal method,under 150-220 ℃ for 16-36 h using Ba（NO3）2 and HfOCl2·8H2O as raw materials,added KOH aqueous solution as precipitant and Ce（NO3）3 aqueous solution as activator.The phase transformation and the morphology of powders during preparation of BaHfO3∶Ce powders were studied by XRD and SEM.The excitation and emission spectra of samples were analyzed by the fluor-photometer.The results show that the powders are approximately spherical particles with even particle size of about 52 nm and good dispersibility under the condition of n（Ba）∶n（Hf）=1∶1,pH=13.5,treated at 200 ℃ for 24 h.The superior photoluminescence properties were obtained at dopping of 0.3 mol % Ce.
