| 英文摘要 | Citric acid chelating method was used to prepare Ce3+ doped BaHfO3 nano-powder. TG-DTA, XRD and SEM were employed to characterize the powder. The excitation and emission spectra of the specimens were analyzed by the fluorescence photometer. Results show that BaHfO3:Ce3+ nanometer powder with high degree of crystallinity, nearly spherical morphology and 40 nm particle size could be synthesized after the precursor gel prepared under the condition of CA:EG=1:3 was calcined at 1050 degrees C for 2 h. The maximum relative intensities of the excitation spectra and emission spectra appeared for the BaHfO3:Ce3+ specimen with Ce3+ doped concentration of 0.9 mol%. The excitation spectrum has two relatively wide spectrum bands where there are maximum peak values at the wavelength of 393 nm and 445 nm, respectively. The emission spectra at lambda(ex)= 393 nm and lambda(ex)=445 nm also have two spectrum bands where exist maximum peak values at 530 nm and 590 nm, respectively, corresponding to 5d -> F-2(5/2) and 5d -> F-2(7/2) transitions of Ce3+ cation, respectively. The emission spectra at 393 nm and 445 nm are obviously different, because the 4f ground State of Ce3+ cation is formed by two energy levels, with the energy difference of about 2000 cm(-1). |
