英文摘要	a series of eu2+-, ce3+-, and tb3+-doped ca2ga2sio7 phosphors is synthesized by using a high-temperature solid-state reaction. the powder x-ray diffraction and structure refinement data indicate that our prepared phosphors are single phased and the phosphor crystalizes in a tetrahedral system with the p (4) over bar 2m (113) space group. the eu2+ - and ce3+-doped phosphors both have broad excitation bands, which match well with the uv light-emitting diodes chips. under irradiation of lambda = 350 nm, ca2ga2sio7:eu2+ and ca2ga2sio7:ce3+, li+ have green and blue emissions, respectively. luminescence of ca2ga2sio7:tb3+, li+ phosphor varies with the different tb3+ contents. the thermal stability and energy-migration mechanism of ca2ga2sio7:eu2+ are also studied. the investigation results indicate that the prepared ca2ga2sio7:eu2+ and ca2ga2sio7:ce3+, li+ samples show potential as green and blue phosphors, respectively, for uv-excited white-light-emitting diodes.
