Improved synthesis of SrLiAl3N4:Eu2+ phosphor using complex nitride raw material
Abstract
Narrow band deep-red emission SrLiAl3N4:Eu2+ phosphor was synthesized using complex nitride Sr3Al2N4 and Li3AlN2 as raw materials. The SrLiAl3N4:Eu2+ phosphor has the oxoplumbate type triclinic structure as the main phase. The phosphor exhibited deep-red emission peaking at 654 nm under excitation at 450 nm and showed an excellent thermal stability on the thermal quenching effect.
