Integrated chemical process for exothermic wave synthesis of high luminance YAG:Ce phosphors

► A new solid-flame strategy was developed for synthesizing high-luminance YAG:Ce phosphor. ► Adding KClO3+CO(NH2)2+NH4F mixture to oxide powders provides a low-temperature combustion process. ► YAG:Ce phosphor particles 10-25 μm in diameter were obtained at 1000-1100 °C within tens of seconds. ► As-prepared YAG:Ce emission intensity was 90.1-103.2% compared to that of the reference sample.
