• A simple, highly efficient method of synthesizing \beta-SiAlON:Eu²⁺phosphors for white light-emitting diodes was reported. The new route was carried out via a combustion synthesis method using Si, SiO<inf>2</inf>, and Al raw materials, and NaCl as a diluent under nitrogen pressure. The phase purity, photoluminescence properties, and thermal quenching of the phosphors were investigated. The results revealed that the synthesized \beta-SiAlON:Eu²⁺powders, which comprised rodlike crystals, exhibited high thermal stability: The emission intensity at 160 °C was 84% of that measured at room temperature, which indicates that the synthesized \beta-SiAlON:Eu²⁺phosphors have high potential for application to white LEDs.
