Abstract:
Eu3+ doped Li3Ba2La3(WO4)(8) red phosphors were synthesized by the solid state reaction method. A pure phase was confirmed by the X-ray diffraction pattern. Diffuse reflection spectra, photoluminescence spectra, decay curves, quantum yields, and temperature-dependence luminescence spectra were measured. The Eu3+ ions can substitute the La3+ ions completely without decreasing the emission intensity obviously and the quantum yields can keep at about 95%. The activation energy from the bottom of D-5(0) level to the D-5(0)-charge transfer state crossover is 0.24eV. All the results indicate that the Eu3+ doped Li3Ba2La3(WO4)(8) can serve as a near ultraviolet excited red phosphor for white light emitting diodes. (C)2015 Optical Society of America
