    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, Sc 2O3 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:Ce 3+. The Ca3Sc2Si3O12: Ce3+ contained only trace of Sc2O3and showed over twice fluorescent intensity than when compared than with that of the solid state reaction samples.
