| 中文摘要 | (zn(1-x-y)mg(y))(2)geo(4): xmn(2+) (y = 0-0.30; x = 0-0.035) phosphors with uniform submicrorod morphology were synthesized through a facile hydrothermal process. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), photoluminescence (pl), and cathodoluminescence (cl) spectroscopy were utilized to characterize the samples. sem and tem images indicate that zn(2)geo(4):mn(2+) samples consist of submicrorods with lengths around 1-2 mu m and diameters around 200-250 nm, respectively. the possible formation mechanism for zn(2)geo(4) submicrorods has been presented. pl and cl spectroscopic characterizations show that pure zn(2)geo(4) sample shows a blue emission due to defects, while zn(2)geo(4):mn(2+) phosphors exhibit a green emission corresponding to the characteristic transition of mn(2+) ((4)t(1) -> (6)a(1)) under the excitation of uv and low-voltage electron beam. compared with zn(2)geo(4):mn(2+) sample prepared by solid-state reaction, zn(2)geo(4):mn(2+) phosphors obtained by hydrothermal process followed by high temperature annealing show better luminescence properties. in addition, codoping mg(2+) ions into the lattice to substitute for zn(2+) ions can enhance both the pl and cl intensity of zn(2)geo(4):mn(2+) phosphors. furthermore, zn(2)geo(4):mn(2+) phosphors exhibit more saturated green emission than the commercial feds phosphor zno:zn, and it is expected that these phosphors are promising for application in field-emission displays. |
