中文摘要	nanocyrstalline tb3+-doped lagao3 phosphors were prepared through a pechini-type sol-gel process. x-ray diffraction, field-emission scanning electron microscopy (fesem), photoluminescence, cathodoluminescence spectra, and lifetimes were utilized to characterize the synthesized phosphors. xrd results reveal that the sample begins to crystallize at 900 degrees c and pure lagao3 phase can be obtained at 1000 degrees c. fesem images indicate that the tb3+-doped lagao3 phosphors are composed of aggregated spherical particles with sizes ranging from 40 to 80 nm. under the excitation of ultraviolet light and low-voltage electron beams (0.5-3 kv), the tb3+-doped lagao3 phosphors show the characteristic emissions from the lagao3 host lattice and the tb3+ (d-5(3,4)-f-7(6,5,4,3) transitions). the emission colors of tb3+-doped lagao3 phosphors can be tuned from blue to green by changing the excitation wavelength of ultraviolet light and the doping concentration of tb3+ to some extent. relevant luminescence mechanisms are discussed.
