摘要：
In this study, Eu3+-doped ZnO-Li3NbO4 phosphors were prepared by the sol-gel method. The physical and luminescence properties of the Eu3+-doped ZnO-Li3NbO4 structure were characterized. The results show the crystallinity of the biphasic ZnO-Li3NbO4 structure sintered at temperatures above 400 degrees C. The main excitation and emission bands of the Eu3+ doped ZnO-Li3NbO4 phosphors were 466 nm (F-7(0)-> D-5(2)) and 615 nm (D-5(0)-> F-7(2)), respectively. When the amount of Eu3+ was 5%, the highest emission intensity was obtained at 595 nm (D-5(0)-> F-7(1)) and 615 nm (D-5(0)-> F-7(2)).
