| 中文摘要 | eu3+ and/or tb3+-doped cayalo4 phosphor samples were synthesized by pechini-type sol-gel method. x-ray diffraction (xrd), field-emission scanning electron microscopy (fe-sem), photoluminescence (pl) and cathodoluminescence (cl) spectra were used to characterize the samples. for cayalo4:tb3+, it is shown that the tb3+-doping concentration has a significant effect on the d-5(3)/d-5(4) emission intensity of tb3+, which is attributed to the cross relaxation from d-5(3) to d-5(4). under the 4f(8) -> 4f(7)5d excitation of tb3+ or low-voltage electron beams excitation, the cayalo4:tb3+ phosphors show tunable luminescence from blue to cyan, and then to green with the change of tb3+-doping concentration. the cayalo4:eu3+ samples exhibit a reddish-orange emission of eu3+ corresponding to d-5(0,1) -> f-7(0,1,2,3) transitions. furthermore, a white emission can be realized in the single phase cayalo4 host by reasonably adjusting the doping concentrations of tb3+ and eu3+ under low-voltage electron beams excitation. compared with the commercial blue (y2sio5:ce3+) and green (zno:zn) phosphors, cayalo4:0.1%tb3+ and cayalo4:5%tb3+ phosphors have higher cl intensity and stability under continuous electron bombardment. due to the excellent cl properties and good cie chromaticity coordinates, the as-prepared tb3+/eu3+-doped cayalo4 nanocrystalline phosphors have potential application in feds devices. |
