| 中文摘要 | a series of eu3+, tb3+, tm3+ singly and triply doped ca3bi(po4)(3) (cbp) phosphors were synthesized by solid-state reaction. their structure and photoluminescence (pl) properties were first investigated in detail. rietveld refinement analysis confirmed that the cbp has a cubic unit cell. its space group was determined to be i (4) over bar 3d with cell parameters a = b = c = 9.941 angstrom and z = 4. in addition, the ca3bi(po4)(3) shows both cation disorder and oxygen sublattice disorder. for the cbp:eu3+ phosphor, the charge transfer bands in the ple spectra were different at 293 k and 4.3 k, and a model was presented to give a possible explanation for this phenomenon. cbp:eu3+ shows intense red emission due to d-5(0)-f-7(2) transition and its integral emission intensity and quantum efficiency are higher than the commercial y2o3:eu3+ phosphor under irradiation of 397 nm, indicating that the cbp: eu3+ phosphor might have potential application in the nuv range for solid-state lighting. the cbp:tb3+ and cbp:tm3+ phosphors show intense green and blue emission due to d-5(4)-f-7(2) transition of the tb3+ ions and the d-1(2)-f-3(4) transition of the tm3+ ions, respectively. the energy transfer from the tb3+ to eu3+ ions was also validated by the spectra and decay curves of the tb3+ ions. tunable emission colors were obtained by triply doping eu3+, tb3+ and tm3+ activators in a single host and adjusting their relative ratio. |
