| 中文摘要 | lagao3:sm3+, lagao3:tb3+ and lagao3: sm3+, tb3+ phosphors were prepared through a pechini-type sol-gel process. x-ray diffraction, field emission scanning electron microscopy, photoluminescence (pl), and cathodoluminescence (cl) spectroscopy were utilized to characterize the synthesized phosphors. under excitation with ultraviolet light (250-254 nm), the lagao3: sm3+, lagao3: tb3+ and lagao3: sm3+, tb3+ phosphors mainly show the characteristic broadband emission (from 300 to 600 nm with a maximum around 430 nm) of the lagao3 host lattice, accompanied by the weak emission of sm3+ ((4)g(5/2) -> h-6(5/2), h-6(7/2), h-6(9/2) transitions) and/or tb3+ (d-5(3,4) -> f-7(6,5,4,3) transitions). however, under excitation by low-voltage electron beams (1-3 kv), the lagao3: sm3+, lagao3: tb3+ and lagao3: sm3+, tb3+ phosphors exhibit exclusively the characteristic emissions of sm3+ and/or tb3+ with yellow (sm3+), blue (tb3+, with low concentrations) and white (sm3+ + tb3+) colors, respectively. |
