Abstract：(Y,Gd)Al3(BO3)4 doped with Ce and Tb were prepared by solid state reaction.The structure, VUV excitation properties, and luminescence properties under VUV excitation were studied.(Y,Gd)Al3(BO3)4 belongs to trigonal crystal system with the space group of R32, and the crystal structure does not change as Tb3+ and Ce3+ ions are doped to the crystal lattice.The host absorption band of (Y,Gd)Al3(BO3)4:Tb moves to longer wavelength as Gd3+ mol concentration increases.The energy transfer between Gd3+ and Tb3+ is very effective, and the samples with high Gd3+ mol concentrations have high radiant efficiencies.It was found that the luminescence of Tb3+ is quenched by Ce3+ in (Y,Gd)Al3(BO3)4:Ce, Tb under VUV excitation.
