摘 要：High quality and monodispersed ScVO4 microcrystals were successfully synthesized via a mild hydrothermal route using NH4VO3 as vanadium source. The X-ray power diffraction（XRD） and field-emission scanning electron microscopy（FE-SEM） results indicated that the size, shape, and phase formation of the ScVO4 microcrystals could be tuned by altering the reaction temperature, reaction time, and p H value of the initial solution. Furthermore, the down- and upconversion luminescence of ScVO4:Ln（Ln=Eu, Dy, Sm, Yb/Ho, Yb/Er, and Yb/Tm） microcrystals were characterized and the respective energy transfer processes were also discussed. The experimental results demonstrated that reactions at 200 oC, 24 h, and pH=6 could generate perfect ScVO4 microcrystals, which were then used for luminescence studies.
