Synthesis of Ca₃Sc₂Si₃O₁₂:Ce³⁺ Using Polymerizable Complex Method

Abstract

Ca₃Sc₂Si₃O₁₂:Ce³⁺ is a green emission phosphor, which can be excited by blue light. This compound may find application as the green component of a white lamp based on downconversion of blue light of LED excitation. Although the use of single-phase Ca₃Sc₂Si₃O₁₂:Ce³⁺ results in an increase in the materials fluorescence intensity, Sc₂O₃ has low chemical reactivity and remains in the mixture as an unreacted impurity.
A polymerizable complex method based on polyester formation between metal-citricacid complexes and propylene glycol was applied to synthesis Ca₃Sc₂Si₃O₁₂:Ce³⁺.
The Ca₃Sc₂Si₃O₁₂:Ce³⁺ contained only trace of Sc₂O₃ and showed over twice fluorescent intensity than when compared than with that of the solid state reaction samples.
