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 ℃. The main excitation and emission bands of the Eu3+-doped ZnO–Li3NbO4 phosphors were 466 nm (7F0→5D2) and 615 nm (5D0→7F2), respectively. When the amount of Eu3+ was 5%, the highest emission intensity was obtained at 595 nm (5D0→7F1) and 615 nm (5D0→7F2).
