AbstractThe SrHfO3:Ce ultramicroballoon particles were prepared by unitary alcohol-thermal method, by using Sr(NO3)(2) and HfOCl2 center dot 8H(2)O as raw materials, using C2H5OH/H2O as solvent, adding KOH aqueous solution as mineralier and Ce(NO3)(3)center dot 6H(2)O as activator. The phase transformation and the morphology of powders were studied by XRD and SEM. The excitation and emission spectra of samples were analyzed by the fluorophotometer. The results show that the powders of SrHfO3:Ce are spherical particles with the size of about 900 nm and good dispersibility under the condition of n(Sr):n(Hf)=1:1, VC2H5OH :V-H2O =4:1, pH=13.5, reacted at 140 degrees C for 4 h. The maximum luminous was obtained at doping of 0.7mol% Ce.
