文摘
High-efficient combustion synthesis was developed to prepare α-SiAlON:Eu phosphors. Phosphors exhibited high purity, nice uniformity and good luminescence property. Distinct impacts of nitrogen pressure and Si particle size were studied. Two factors play vital roles in phase composition and grain morphology of products. Appropriate N2 pressure and Si particle size enhanced the luminescence properties.
