摘　　要：Highly efficient phosphors under vacuum ultraviolet excitation are still demanded for the development of plasma display panels and Hg-free fluorescent lamps. The phosphors of Eu3＋ doped （Y, Gd, Lu）BO3 were synthesized with solid state reaction method and the contents of y3＋ Gd3＋, and Lu3＋ for plasma display panel red phosphor were optimized under vacuum ultraviolet excitation. Two new potential candidates, which were （Y1-S-TGdsLuT）BO3： Eu^3＋ （0〈S〈0.2, 0〈T〈0.1） and （GdlYJLuK）BO3： Eu3＋ （0.5〈I〈0.7, 0.2〈J〈0.4, 0〈K〈0.1）, were olgtained. The mechanism of luminescence improvement was discussed upon the analysis of crystal microstructure and excitation spectra.Highly efficient phosphors under vacuum ultraviolet excitation are still demanded for the development of plasma display panels and Hg-free fluorescent lamps.
