YAG:Ce phosphor were prepared in a self-propagating high-temperature synthesis (SHS) using a
1.5Y2O3+2.5Al2O3+0.116CeO2+3.0KClO3+kCO(NH2)2+m(C2F4)n precursor mixture. The heat for the
combustion propagation was provided by the reaction of a KClO3+CO(NH2)2+(C2F4)n mixture. Pure-phase
YAG phosphor was synthesized at the combustion temperature of 1210℃ from k=3.6 mole and m=0.3 mole.
The as-prepared YAG:Ce phosphor had a particle size of 2-10 ㎛. The addition of Teflon to the precursor mixture increased the YAG particle size and its luminescent intensity. The emission peak of the YAG
phosphor was blue-shifted with an increase of Teflon concentration.
