Abstract

The luminescence of Ce³⁺ in host lattices based on Y₃Al₅O₁₂ garnets that can be used in blue LED based solid state lighting sources is discussed. Specifically, the effect of Ga³⁺ and Tb³⁺ substitution for Al³⁺ and Y³⁺, respectively, on the emission color and thermal quenching of these phosphors is described with the initial implications for white light devices.
