CaAl12O19: Mn4+ has been reported as a red phosphor with good color purity. A quaternary-doping strategy was adopted to improve the optical properties in this work. Phosphors of general formula Ca1-mAl12-x-y-nO19: xMn4+, yMg2+, mBi3+, nB3+ (CAO:MMBB) were synthesized by high-temperature solid-state...
