| 中文摘要 | highly crystalline camoo4:tb3+ phosphor layers were grown on monodisperse sio2 particles through a simple sol-gel method, resulting in formation of core-shell structured sio2@camoo4:tb3+ submicrospheres. the resulting sio2@camoo4: tb3+ core-shell particles were fully characterized by powder x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), field emission scanning electron microscopy (fesem), energy-dispersive x-ray spectra (eds), transmission electron microscopy (tem), photoluminescence (pl), low-voltage cathodoluminescence (cl), and kinetic decays. the xrd results demonstrate that the camoo4:tb3+ layers begin to crystallize on the sio2 spheres after annealing at 400 degrees c and the crystallinity increases with raising the annealing temperature. sem and tem analysis indicates that the obtained submicrospheres have a uniform size distribution and obvious core-shell structure. sio2@camoo4:tb3+ submicrospheres show strong green emission under short ultraviolet (260 nm) and low-voltage electron beam (1-3 kv) excitation, and the emission spectra are dominated by a d-5(4) -f-7(5) transition of tb3+(544 nm, green) from the camoo4:tb3+ shells. |
