Abstract

Different fluxes were added in preparation of Ca₃Sc₂Si₃O₁₂:0.01Ce ³⁺ 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 Ca₃Sc₂Si₃O₁₂:0.01Ce ³⁺ phosphors remarkably. White light-emitting diode was fabricated with the Ca₃Sc₂Si₃O₁₂:0.01Ce ³⁺ 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.
