| 摘 要： | A series of Tb^3＋ doped Na Y（Mo O4）2 are synthesized by a solid-state reaction at 550 °C for 4 h, and their luminescent properties are investigated. The phase formation is carried out with X-ray powder diffraction analysis, and there is no other crystalline phase except Na Y（Mo O4）2. Na Y（Mo O4）2：Tb^3＋ can produce the green emission under 290 nm radiation excitation, and the luminescence emission peak at 545 nm corresponds to the 5D4→7F5 transition of Tb^3＋. The emission intensity of Tb^3＋ in Na Y（Mo O4）2 is enhanced with the increase of Tb^3＋ concentration, and there is no concentration quenching effect. The phenomena are proved by the decay curves of Tb^3＋. Moreover, the Commission International de I＇Eclairage（CIE） chromaticity coordinates of Na Y（Mo O4）2：Tb^3＋ locate in the green region.
