Abstract :
Yttrium aluminum garnet Y3Al5O12 (YAG) phosphor, activated with trivalent cerium (Ce3+) was synthesized using different aluminum sources by microwave and conventional furnace. The crystallization, morphologies, particle size, and luminescent properties of the phosphors were investigated and discussed. A pure YAG:Ce phase with no second phase was successfully formed when aluminum sources, aluminum nitrate, was used and sintered at 1500°C for 5 h by microwave assisted furnace. The uniform grain size distribution and well luminescent property were obtained when the YAG phosphors were sintered by microwave assisted sintering using aluminum nitrate as the aluminum sources.
