AbstractSrGdGa3O7:RE (RE=Ce3+, Pr3+, Tb3+) were prepared by traditional solid-state reaction and their luminescence properties in the range of VUV-Vis were investigated. The two broad bands situated at about 177 and 217 nm in excitation spectra are attributed to the host lattices absorption, and they have no considerable change when doped different rare earth ions. The f-d transitions of Pr3+ and Tb3+ calculated by the formula gathered by Dorenbos were compared to the experimental results. The excitation spectra also show the sharp Gd3+ excitation line at about 274 nm pointing to an efficient energy transfer from Gd3+ to Pr3+ and Tb3+. All of the emission spectra present the characteristic emissions of rare earth ions when excited by VUV and UV.
