N2 - A series of double perovskite (Gd1−xTbx)2MgTiO6 (x = 0.01, 0.05, 0.1, 0.15, 0.2, 0.3 and 0.4) phosphors were successfully synthesized by solid-state reaction method. The A-site in the host is occupied by two Gd3+ ions, which facilitates the doping of Tb3+ ions. The crystal structure, morphology and luminescence performance were evaluated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, photoluminescence and calculation of CIE color coordinates. A weak emission peak (5D4–7F6, 490 nm) and a strong emission peak (5D4–7F5, 545 nm) existed in the emission spectra under 313 nm excitation. The quenching concentration of Tb3+ reached up to 20.0 mol% was observed in Gd1.8Tb0.2MgTiO6 phosphors. In order to explore the potential application of Gd2−2xMgTiO6:xTb3+ phosphors in white LED solid-state lighting, the fluorescence decay curves and thermal stability were carried out.
