Description

Different fluxes were added in preparation of Ca3Sc2Si3O12:0.01Ce3+ phosphors with a solid-state method and the different influences of the fluxes on phase formation, morphology, and photoluminescence properties of the phosphors were studied. The results show that CaF2 flux is the best flux as it can decrease single phase-forming temperature, improve morphology and enhance photoluminescence of the Ca3Sc2Si3O12:0.01Ce3+ phosphors remarkably. White light-emitting diode was fabricated with the Ca3Sc2Si3O12:0.01Ce3+ phosphor prepared with CaF2 flux, and good performances of this WLED confirm that CaF2 is a good flux for preparing Ca3Sc2Si3O12:Ce3+, and the phosphor is an efficient green component for fabrication of white LEDs.
