| 中文摘要 | nearly monodisperse ybo3 architectures with various shapes have been prepared on a large scale by a facile, effective, and environmentally friendly hydrothermal process using y(oh)(3) as a precursor. x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (sem), transmission electron microscopy (tem), high-resolution transmission electron microscopy (hrtem), photoluminescence (pl) and cathodoluminescence (cl) spectra were used to characterize the samples. the shape and size of these as-prepared ybo3 architectures can be tuned effectively by controlling the reaction conditions, such as reaction time, and the molar ratio of h3bo3/y(oh)(3). as a typical morphology, the possible formation mechanism for ybo3 monodisperse flower-like microstructures is presented in detail. to extend this method, other lnbo(3) (ln = dy, ho, er) architectures with well-defined shape and dimensionality can also be achieved by adjusting different rare-earth hydroxides precursors. under uv excitation and low-voltage electron beam excitation, ybo3: 5 mol % eu3+ sample exhibits a strong red emission lines of eu3+ corresponding to d-5(0) -> f-7(j) (j = 0-4) transitions. when doped with 5 mol % tb3+ ions, the emission lines of tb3+ corresponding to d-5(4) -> f-7(j) (j = 6, 5, 4, 3) transitions with d-5(4) -> f-7(5) (green emission at 542 nm) being the most prominent group have been observed. this work sheds some light on the design of a well-defined complex nanostructure, and the luminescent properties have potential applications in fluorescent lamps and field emission displays. |
