AbstractBaHfO3:Ce nanoparticles were synthesized by the process of solid-state reaction. Both XRD and SEM were adopted to analyze the phase change and the characteristics of BaHfO3:Ce nano-powders during calcining process. Excitation and emission spectra were analyzed separately with the fluorescence photometer. The result shows that the average diameter of the BaHfO3:Ce nano-powders being approximate to spherical morphology is about 30 nm and the powders have good dispersibility after calcining at 1000 degrees C for 2 h. It also shows that there is no change happened on the cubic crystal structure even though a little amount of Ce3+ ion added to the powders can lead to the lattice distortion of BaHfO3 matrix material. The excitation spectrum of BaHfO3: Ce nanoparticles has two excitation peaks separately at 396 nm and 446 nm points. The emission spectrum excited by the 396 nm light consists of two emission bands, peaking at 531 nm and 591 run, respectively, the emission character of which changes from the 5d -> F-2(5/2) to 5d -> F-2(7/2) transitions of Ce3+ cation. When the emission spectrum is excited by the 446 nm light, only one wide emission peak at 591 nm point exists and the other one at around 531 nm becomes flat. When the Ce3+ dopant content is 0.9%(molar fraction), the figure of the emission peak reaches its highest point. This figure, however, drops when The Ce3+ dopant content is 1.1%( molar fraction), which is resulted from the concentraction quenching.
