ABSTRACT

Yttrium aluminum garnet (YAG) and Lutetium aluminum garnet (LuAG) doped with Ce3+ are widely applied phosphor powders or ceramics for the conversion of blue into green to yellow light in the rapidly expanding market of white light emitting high power LEDs. Surprisingly, the temperature dependent reflection and excitation spectra of these well-established materials have not been investigated until today. In this work, we report the temperature dependence of the reflection and excitation spectra of Ce3+ doped YAG and LuAG in the temperature range from 300 to 800 K.
