Luminescence properties of YBO3-GdBO3 solid solutions doped with Tb3+ have been investigated in order to understand the energy transfer processes between Gd3+ and Tb3+ in these phosphors. The critical atomic fraction (Xc) and the critical distance (Rc) for efficient energy migration among Gd3+ ions were derived. In YBO3-GdBO3:Tb solid solutions, (Gd3+-BO33-) absorbs excitation energy more efficiently than (Y3+-BO33-) in the VUV region.
