文摘

The phosphate glass doped with Gd³⁺, Tb³⁺ and Gd³⁺/Tb³⁺ were prepared by high temperature melting. The photo-luminescence behavior of Gd³⁺ and Tb³⁺ in phosphate glass were investigated by absorption, excitation, and emission spectroscopy. Energy transfer between Gd³⁺ and Tb³⁺ in phosphate glass was studied, and it was found that there were two energy transfer mechanisms between Gd³⁺ and Tb³⁺ in phosphate glass: one was from 4f⁷ level of Gd³⁺ to the 4f⁸ level of Tb³⁺, and the other was from 5d level of Tb³⁺ to 4f⁷ level of Gd³⁺. The new findings would be beneficial for the study of Tb³⁺-doped scintillating phosphate glass.
