文摘
- •
Combustion synthesis was developed to fabricate Eu-doped Ca-伪-SiAlON phosphors.
- •
Products possessed high purity, uniform morphology and good luminescence property.
- •
NH4Cl was applied as a unique additive to obtain products with high quality.
- •
The addition of NH4Cl remarkably promoted the luminescence properties of products.
- •
Two contradictory influence mechanisms of NH4Cl additive were rationally proposed.
