| 中文摘要 | caln(2)o(4):dy3+/pr3+/tb3+ blue-white/green/green phosphors were prepared by the pechini sol-gel process. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), diffuse reflectance, photoluminescence (pl) and cathodoluminescencc (cl) spectra as well as lifetimes were utilized to characterize the samples. the xrd results reveal that the samples begin to crystallize at 800 degrees c 3-1 and pure cain2o4 phase can be obtained after annealing at 900 degrees c. the fe-sem images indicate that the cain2o4:dy3+, cain2o4:pr3+ and cain2o4:tb3+ samples consist of spherical grains with size around 200-400nm. under the excitation of ultraviolet light and low electron beams (1-5kv), the cain2o4:dy3+, cain2o4:pr3+ and cain2o4:tb3+ phosphors show the characteristic emissions of dy3+ ((f9/2-h15/2)-f-4-h-6 and (f9/2-h13/2)-f-4-h-6 transitions, blue-white), pr3+ ((p0-h4)-p-3-h-3, (d2-h4)-d-1-h-3 and (p1-h5)-p-3-h-3 transitions, green) and tb3+ ((d4-f6,5,4,3)-d-5-f-7 transitions, green), respectively. all the luminescence is resulted from an efficient energy transfer from the cain2o4 host lattice to the doped dy3+ ,pr3+ and tb3+ ions, and the corresponding luminescence mechanisms have been proposed. |
