| 中文摘要 | laalo3:tm3+ and laalo3:tb3+ phosphors were prepared through a pechini-type sol-gel process. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), photoluminescence, and cathodoluminescence (cl) spectra were utilized to characterize the synthesized phosphors. the xrd results reveal that the fully crystalline pure laalo3 phase can be obtained at 800 degrees c. the fe-sem image indicates that the phosphor samples are composed of aggregated spherical particles with sizes ranging from 40 to 80 nm. under the excitation of ultraviolet light (230 nm) and low-voltage electron beams (1-3 kv), the laalo3:tm3+ and laalo3:tb3+ phosphors show the characteristic emissions of tb3+ (d-1(2)-> h-3(6,4),f-3(4) transitions) and tm3+ (d-5(3,4)-> f-7(6,5,4,3) transitions) respectively. the cl of the laalo3:tm3+ phosphors have high color purity and comparable intensity to the y2sio5:ce3+ commercial product, and the cl colors of tb3+-doped laalo3 phosphors can be tuned from blue to green by changing the doping concentration of tb3+ to some extent. |
