Abstract

Development of orange light emitting materials cannot be ignored. In this paper, a novel Tb3+/Sm3+ co-doped P2O5-SrO-BaO-ZnO-glasses have been prepared. The prepared glasses consisted predominantly of Q2 units, and a small amount of Q0 and Q1 units. For absorption spectra of glasses, eight obvious absorption bands were found. Under the excitation of 402 nm and 374 nm xenon lamp, the emission spectra and fluorescence lifetimes of glasses showed big difference. Under the excitation of 374 nm xenon lamp, there was significant energy transfer process between Sm3+ and Tb3+ ions in glasses. The fluorescence decay curves conformed to a double-exponential decay function, the average fluorescence lifetimes of glasses G02 ~ G10 were 2.38 ms, 2.67 ms, 1.96 ms, 1.81 ms, and 1.61 ms with the increasing of Sm2O3 content, and the glasses emitted a distinct orange light. The distinctive properties indicate that this system glass has potential applications in display devices
