A series of single-phase Sr2YNbO6(SYNO): Bi3+, Eu3+ phosphors for light-emitting diode applications were synthesized by high-temperature solid state reactions. The XRD measurement indicated that the doping of Bi3+ and Eu3+ did not change crystal structure of the phosphors. The results show that the optimum doping concentrations of Bi3+ and Eu3+ ions are 0.03 and 0.12, respectively. The emission color of the SYNO: 0.03Bi3+, 0.12Eu3+ phosphor can be adjusted from green to white to purple and blue by selecting appropriate excitation wavelengths in near-UV or the suitable Eu3+ doping contents. Especially, the white emission light is obtained when the excitation wavelength changes from 355 to 360 nm. All results indicate that Sr2YNbO6: Bi3+, Eu3+ phosphor has a vast application prospect and preponderance in the field of white light-emitting diodes.
Sr2YNbO6: Bi3+, Eu3+, White light-emitting diodes, Phosphors.
