中文摘要	uniform and well-dispersed srf2 hierarchical microspheres have been successfully synthesized by a facile and friendly hydrothermal method. the experimental results indicate that such 3d hierarchical srf2 microspheres with size about 1 mu m are assembled by numerous nanocrystals (about 100 nm). nitrogen adsorption-desorption measurement suggests that mesopores exist in these hierarchical microarchitectures. the formation process of the hierarchical srf2 microspheres and luminescence properties of srf2:ln(3+) (ln = ce, tb, yb, er) microspheres have been investigated in detail. it is found that reaction time and trisodium citrate play a key role in forming the hierarchical microspheres. in addition, the lanthanide ions (ln(3+))-doped srf2 hierarchical microspheres show strong green (ln(3+) = ce3+, tb3+) photoluminescence with 45% quantum efficiency and cathodoluminescence centered at 542 nm corresponding to the d-5(4) -> f-7(5) transition of tb3+ under excitation of ultraviolet light and low-voltage electron beam, respectively. in addition, srf2:yb3+,er3+ hierarchical microspheres show bright yellow upconversion emission under 980 nm laser diode excitation. the as-synthesized srf2:ln(3+) luminescent microspheres might find some potential applications in areas of photoluminescence and field emission displays.
