| 中文摘要 | in this paper, highly uniform and well-dispersed caf2 microsphere with tunable particles size have been successfully synthesized by a facile hydrothermal process using ethylenediaminetetraacetic acid disodium as a complexing reagent. the xrd results indicated that the as-prepared microspheres were of cubic phases and had good crystallinity and purity. the tem and sem results reveal that monodisperse and uniform hollow sphere with rough surfaces can be prepared by this approach. in addition, ce3+/tb 3+-codoped caf2 sphere can be prepared similarly. excitation and emission spectra are shown that the samples can absorb ultraviolet light and emit light at 335 nm. in the emission spectrum, it is clear that emission intensity of ce3+ decreases with increasing tb3+, it shows that efficient energy transfer from ce3+ to tb3+ may occur. it significantly improves the absorption range and intensity of the samples. that is extremely useful and has potential application value in display, light, laser, optical information transfer, scintillator and optoelectronic devices. |
