✦ Synopsis

Ce doped yttrium aluminium garnet (YAG:Ce) was synthesized by LiF assisted sol-gel combustion method. The thermal behavior, composition, and microstructure feature of the precursor were studied by TG/DTA, XRD, PL, and SEM. The using of LiF in the sol-gel combustion process was helpful to decrease the sintering temperature about 200 °C. The X-ray diffraction patterns of the powder sintered at 540 °C were identical with the stoichiometric YAG composition, which was the lowest temperature reported for the synthesis of crystalline and single phase YAG.
