| 中文摘要 | nanocyrstalline lagao3 and dy3+- and eu3+-doped lagao3 were prepared through a pechini-type sol-gel process. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), photoluminescence, cathodoluminescence spectra, and lifetimes were utilized to characterize the samples. xrd reveals that the samples begin to crystallize at 900 degrees c and pure lagao3 phase can be obtained at 1000 degrees c. fe-sem images indicate that the dy3+- and eu3+-doped lagao3 samples are both composed of aggregated spherical particles with sizes ranging from 40 to 80 nm. under the excitation of ultraviolet light and low voltage electron beams (1-5 kv), the undoped lagao3 sample shows a strong blue emission peaking at 433 nm, and the dy3+- and eu3+-doped lagao3 samples show their characteristic emissions of dy3+ (f-4(9/2)-h-6(15/2) and f-4(9/2)-h-6(13/2) transitions) and eu3+ (d-5(0,1,2)-f-7(1,2,3,4) transitions), respectively. the relevant luminescence mechanisms are discussed. |
