| 中文摘要 | one-dimensional tb(2)(wo(4))(3) and tb(2)(wo(4))(3):eu(3+) nanowires have been prepared by a combination method of sol-gel process and electrospinning. x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), photoluminescence (pl), low voltage cathodoluminescence (cl) and time-resolved emission spectra as well as kinetic decays were used to characterize the resulting samples. the as-obtained precursor samples present fiber-like morphology with uniform size, and tb(2)(wo(4))(3) and tb(2)(wo(4))(3):eu(3+) nanowires were formed after annealing. under ultraviolet excitation and low-voltage electron beams excitation into wo(4)(2-) and the f-f transition of tb(3+), the tb(2)(wo(4))(3) samples show the characteristic emission of tb(3+) corresponding to (5)d(4)-(7)f(6, 5, 4, 3) transitions due to an efficient energy transfer from wo(4)(2-) to tb(3+), while tb(2)(wo(4))(3):eu(3+) samples mainly exhibit the characteristic emission of eu(3+) corresponding to (5)d(0)-(7)f(0, 1, 2) transitions due to an energy transfer occurs from wo(4)(2-) and tb(3+) to eu(3+). the increase of eu(3+) concentration leads to the increase of the energy transfer efficiency from tb(3+) to eu(3+). the pl color of tb(2)(wo(4))(3):x mol% eu(3+) phosphors can be tuned from green to red easily by changing the doping concentration (x) of eu(3+), making the materials have potential applications in fluorescent lamps and color display fields. |
