| 英文摘要 | a series of ln(3+) (ln(3+) = eu3+/tb3+/dy3+/sm3+) ion doped canb2o6 (cno) phosphors have been prepared via the conventional high-temperature solid-state reaction route. the x-ray diffraction (xrd) and structure refinement, diffuse reflection, photoluminescence (pl), and fluorescent decay curves were used to characterize the as-prepared samples. under uv radiation, the cno host present a broad emission band from about 355 to 605 nm centered around 460 nm originating from the nbo6 octahedral groups, which has spectral overlaps with the excitation of f-f transitions of eu3+/tb3+/dy3+/sm3+ in cno:eu3+/tb3+/dy3+/sm3+ samples. they show both host emission and respective emission lines derived from the characteristic f-f transitions of activators, which present different emission colors owing to the energy transfer from the nbo6 group in the host to eu3+/tb3+/dy3+/sm3+ with increasing activator concentrations. the decreases of decay lifetimes of host emissions in cno:eu3+/tb3+/dy3+/sm3+ demonstrate the energy transfer from the hosts to eu3+/tb3+/dy3+/sm3+. the energy transfer mechanisms in cno:eu3+/tb3+/dy3+ phosphors have been determined to be a resonant type via dipole-dipole mechanisms. for cno:sm3+, the metal-metal charge transfer transition (mmct) might contribute to the different variations of decay lifetimes and emission intensity from cno:eu3+/tb3+/dy3+ samples. the best quantum efficiency is 71.2% for cno:0.01/0.02dy(3+). the pl properties of as-prepared materials indicate the promising application in uv-pumped white-emitting lighting diodes field. |
