英文摘要：

The sulfate ions modified YAG：Ce~（3＋） phosphors were prepared by co-precipitation method and characterized by X-ray diffraction,transmission electron microscopy,and photoluminescence.Effects of sulfate ions on the photoluminescence（PL） property of the as-prepared YAG：Ce~（3＋） phosphors were studied,with sodium dodecyl sulfate（SDS） being added to R~（3＋）（Ce~（3＋）,Y~（3＋）,Al~（3＋）） ions.Results indicated that pure YAG：Ce~（3＋） phosphors with different ratios of sulfate ions could be easily obtained by calcining the as-synthesized precursor at 950 ℃ for 2 h,the YAG：Ce~（3＋） phosphors with an optimal mass ratio of 3.5 wt.%SDS had the highest emission intensity and the best dispersion behavior,and the fluorescence decay of the as-obtained YAG：Ce~（3＋） phosphors was related to the lattice defect,reabsorption and cross correlation.Furthermore,thermal quenching properties of the YAG：Ce~（3＋） phosphors and the YAG：Ce~（3＋） phosphors with 3.5 wt.%SDS were also discussed,indicating that the YAG：Ce~（3＋） with SDS phosphors could have potential applications in the daylight LEDs or warm white LEDs.
