Abstract: The phosphors BaAl12O19:Tb and BaAl12O19:Eu were synthesized by sol-gel method, and the effects of B3+ doping on the crystal line structure and luminescent properties of them were studied. The results showed that B3+ doping doesn't affect the BaAl12O19 structure but improves their luminescent intensity. However, B3+ doping plays more obvious role in improving the luminescent intensity of BaAl12O19:Tb than in that of BaAl12O19:Eu and the effective B3+ doping dose for the former is obviously greater than that for the latter. The optimum B3+ doping doses are 50 mol% and 20 mol% for BaAl12O19:Tb and BaAl12O19:Eu, respectively.
