    A series of Y2(0.97-x)Dy0.06MgTiO6∶2xEu3+(YMT∶0.06Dy3+, 2xEu3+) phosphors were successfully synthesized by sol-gel method. The effect of Dy3+, Eu3+ co-doping on phase, microstructure and fluorescence properties of samples was investigated. The results show that the prepared YMT∶0.06Dy3+, 2xEu3+ phosphors are double perovskite structure (crystallized in monoclinic space group P21/n) and the particle size is 1~2 μm. Under the excitation of 262 nm ultraviolet light, the emission spectra show a typical linear characteristic spectra of Dy3+ and Eu3+. The main emission peaks are located at 483(4F9/26H15/2), 579(4F9/26H13/2) and 619 nm (5D07F2), respectively. There is a significant energy transfer between Dy3+ and Eu3+, which is mediated by electric dipole-electric dipole (d-d) interaction. The luminescence intensity of the obtained phosphors at 423 K could remain 74.36% of that at room temperature, showing excellent thermal stability. By changing the concentration of Eu3+, the luminescence color of phosphors shift from yellow region to orange-red spectral region. YMT∶0.06Dy3+, 2xEu3+ phosphors are expected to be candidate materials for solid-state LED lighting.
