Paper 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.
