中文摘要 | sr(3)alo(4)f:re(3+) (re = tm/tb, eu, cc) phosphors were prepared by the conventional solid-state reaction. x-ray diffraction (xrd), field-emission scanning electron microscopy (fe-sem), photoluminescence (pl) spectra, as well as lifetimes were utilized to characterize samples. under the excitation of uv light, sr(3)alo(4)f:tm(3+), sr(3)alo(4)f:tb(3+), and sr(3)alo(4)f:eu(3+) exhibit the characteristic emissions of tm(3+) ((1)d(2)->(3)f(4), blue), tb(3+) ((5)d(4)->(7)e(5), green), and eu(3+) ((5)d(0)->(7)f(2), red), respectively. by adjusting the doping concentration of eu(3+) ions in sr(3)alo(4)f:0.10tm(3+), 0.10tb(3+), zeu(3+), a white emission in a single composition was obtained under the excitation of 360 nm, in which an energy transfer from tb(3+) to eu(3+) was observed. for sr(3)alo(4)f:ce(3+),tb(3+) samples, the energy transfer from ce(3+) to tb(3+) is efficient and demonstrated to be a resonant type via a dipole-quadrupole interaction by comparing the experimental data and theoretical calculation. furthermore, the critical distance of the ce(3+) and tb(3+) ions has also been calculated to be 9.05 angstrom. the corresponding luminescence and energy transfer mechanisms have been proposed in detail. these phosphors might be promising for use in near-uv leds. |
