| heal.abstract | The direct silicon nitridation method was used to synthesize Ca-a-sialon:Eu2+ phosphors. From a low cost CaCO3 AlF3 Si mixture, pure asialon phase was produced at a low temperature of 1250 8C. The crystallinity of the obtained phosphors can be markedly improved by increasing the firing temperature or post-annealing. Solid gas reactions occur easily, according to thermodynamic analysis, leading to loss of silicon and enhancing the replacement of Si N bonds by Al N bonds. The produced Ca-a-sialon:Eu2+ phosphors feature high purity, uniform and discrete particle morphology with a particle size of 1 2 mm and good luminescence properties with a yellow emission that peaks at 580 nm under n-UVor blue light excitation. | en |
