英文摘要	a series of eu2+ and ce3+/tb3+ doped ca2nasio4f (cnsof) phosphors have been synthesized and their structure and photoluminescence properties have been investigated in detail. rietveld structure refinement indicates that the phosphors crystalized in an orthorhombic system with a space group of pnma (no. 62) and there are two kinds of cation sites for the doped ions to occupy in forming emission centers. the cnsof:eu2+ and cnsof:ce3+ phosphors both have broad excitation bands, which match well with the commercial uv led chips. the cnsof:eu2+ phosphor can have intense green emission with a maximum at 530 nm under irradiation at 380 nm, while the cnsof:ce3+ sample can emit intense blue light, peaking at 470 nm with excitation at 365 nm. by codoping the tb3+ and ce3+ ions into an cnsof host and varying their relative ratio, tunable blue-green colors are obtained due to efficient energy transfer from the ce3+ to tb3+ ions. moreover, energy transfer mechanisms for the eu2+ ions in cnsof:eu2+ and ce3+ -> tb3+ in cnsof:ce3+,tb3+ have been studied systematically. our investigation indicates that cnsof:eu2+ and cnsof:ce3+,tb3+ may be potential green and blue-green phosphors for uv wleds, respectively.
