摘要：

A series of Tb3+ doped NaY(MoO4)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 NaY(MoO4)2. NaY(MoO4)2:Tb3+ 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 Tb3+. The emission intensity of Tb3+ in NaY(MoO4)2 is enhanced with the increase of Tb3+ concentration, and there is no concentration quenching effect. The phenomena are proved by the decay curves of Tb3+. Moreover, the Commission International de I’Eclairage (CIE) chromaticity coordinates of NaY(MoO4)2:Tb3+ locate in the green region. © 2014, Tianjin University of Technology and Springer-Verlag Berlin Heidelberg.
