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.
