摘要：

The synthetic compounds of Sb3+ ion-substituted lanthanide aluminum garnet doped with cerium powders have been prepared by solvothermal method at 230 degrees C and then calcined at 1500 degrees C. These particles have spherical morphology with an average size of about 2 mu m, which indicates the good luminescent characteristics. Tb-3(SbAl)Al3O12:Ce3+, and Gd-3(SbGa)Al3O12:Ce3+ showed not only the red shift but also increased broadness with increased red to green ratio as compared with YAG:Ce3+ phosphor. The color coordination of Ce3+-doped Y3Al2Al3O12, Tb-3(SbAl)Al3O12, and Gd-3(SbGa)Al3O12 are (0.315, 0.341), (0.332, 0.331), and (0.337, 0.330), respectively. These results demonstrate that the possibility for the use of Tb-3(SbAl)Al3O12 and Gd-3(SbGa)Al3O12 phosphors to enhance the white light generation in the field of white light-emitting diodes.
