- •
The brightness of SrAl2O4:Eu, Dy reached the maximum 12,101 mcd/m2 at 1300 °C.
- •
The brightness of SrAl2O4 powder reduced with decrease of the crushed granularity.
- •
The co-doping amount of Dy-Tb-Si in SrAl2O4:Eu was optimized by response surface.
- •
The brightness of co-doped phosphors increased, emission peak and intensity changed.
