Abstract
Ce-, Tb-doped and co-doped YBO3 were prepared by solid-state reaction. The structure of the powder is identified as vaterite-type structure. The photoluminescence of the samples under UV/ VUV excitation were investigated. The results indicate that the energy is transferred between Ce3+ and Tb3+ under UV excitation while Ce3+ is not beneficial to the emission of Tb3+ under VUV excitation due to the different luminescence mechanism. The blue emission of Tb3+ was observed at low Tb3+ concentration and disappeared at high activator concentration due to the relaxation.
