Abstract

The yellow-emitting phosphor [Ca _3-(x0.06)Lu _xCe _0.06](Sc _2-yMg _y)Si ₃O ₁₂ obtained from Lu ³⁺ and Mg ² co-modified green-emitting silicate garnet Ca ₃Sc ₂Si ₃O ₁₂:Ce ³⁺ (CSS:Ce ³⁺) exhibits promising applications for white LEDs. In this paper, we discuss the effect of charge balance on the garnet structure formation. The changes of bond length and covalence caused by the replacement of Lu ³⁺ and Mg ² for Ca ² and Sc ³⁺ are analyzed. The shift of the Ce ³⁺ emission and excitation can be attributed to the combined results from crystal field splitting effect and centroid shift of Ce ³⁺ 5d levels. Thermal stability is analyzed according to configurational coordinate diagram.
