Abstract: 본발명의일 실시예에따른사이알론형광체제조방법은, 규소전구체및 알루미늄전구체를혼합한후 소결하여제1 소결체를형성한후에, 상기제1 소결체및 활성물질의전구체를혼합한후 열처리하여제2 소결체를형성한다. 즉, 일실시예에따른형광체제조방법은호스트물질인제1 소결체를먼저형성하여결정구조를안정적으로확보한후에활성물질을제1 소결체에혼합함으로써제1 소결체의결정구조를깨뜨리지않으면서활성물질의역할을수행할수 있다. 결국, 제1 소결체의결정구조에서활성물질이 Si나 Al 자리가아닌공극(empty sphere)에위치함으로써제1 소결체의결정성이저해되는것을억제할수 있다. 또한, 상기와같은제조방법에의해제조된사이알론형광체는결정구조면에서안정성이확보되어있고, 고온에서도열 안정성이우수하여, 장시간동안작동하더라도수명열화로인한효율감소가매우적다. 또한, 상기와같은제조방법에의해제조된사이알론형광체를포함하는발광소자패키지는, 사이알론형광체의결정구조가안정적이기때문에, 결정성저해로인해휘도가감소하는것을방지할수 있다.
