| Abstract: | (Y,Gd)BO_3Eu powders were prepared with the conventional solid-reaction method. Surface-modified (Y,Gd)BO_3Eu powders with MgF_2 were prepared by the emulsion method. The best preparing way is that MgCl_2 was dropped to the mixture of NH_4F and (Y,Gd)BO_3Eu powders to prepare surface-modified (Y,Gd)BO_3Eu powders. The interaction between F~- ions and the phosphor particles was discussed. The structures of surface-modified (Y,Gd)BO_3Eu powders were measured by XRD, IR, excitation spectra and {emission} spectra. |

| Keywords: | (Y Gd)BO_3Eu phosphor coated MgF_2 excitation spectrum emission spectrum |
