摘要：
In this study,a single-doped phosphors yttrium aluminum garnet(Y3Al5O12,YAG):Ce3+,single-doped YAG:Sc3+,and double-doped phosphors YAG:Ce3+,Sc3+were prepared by spark plasma sintering(SPS)(lower than 1 200℃).The characteristics of synthesized phosphors were determined using scanning electron microscopy(SEM),X-ray diffraction(XRD),and fluorescence spectroscopy.During SPS,the lattice structure of YAG was maintained by the added Ce3+and Sc3+.The emission wavelength of YAG:Ce3+prepared from SPS(425-700 nm) was wider compared to that of YAG:Ce3+prepared from high-temperature solid-state reaction(HSSR)(500-700 nm).The incorporation of low-dose Sc3+in YAG:Ce3+moved the emission peak towards the short wavelength.
