| 中文摘要 | gdof:ln(3+) (ln = eu, tb, tm, dy, ho and sm) microspheres (1.5 mu m) with high uniformity and monodispersity have been synthesized via a facile hydrothermal method followed by heat treatment (600 degrees c). x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (sem), transmission electron microscopy (tem), as well as photoluminescence (pl) and cathodoluminescence (cl) spectra are used to characterize the resulting samples. a series of controlled experiments indicate that sodium citrate (cit(3-)) as a shape modifier introduced into the reaction system plays a critical role in the shape evolution of the final products. furthermore, the shape and size of the products can be further manipulated by adjusting the dosage of cit(3-) and ph values in the initial solution. the possible formation mechanism for these microspheres has been presented. under uv light and low-voltage electron beam excitation, gdof:ln(3+) microspheres show the characteristic f-f transitions of ln(3+) (eu, tb/ho, tm, dy and sm) ions and give bright red, green, blue, yellow and yellowish-orange emission, respectively. in addition, multicolored luminescence containing white emission have been successfully confected for co-doped gdof:ln(3+) phosphors by changing the doped ln(3+) ions and adjusting their doping concentrations due to the simultaneous luminescence of ln(3+) in the gdof host, making these materials have potential applications in field-emission display devices. |
