B(上标 3+)对掺杂Tb(上标 3+)/Eu(上标 2+)的BaAl12O19荧光材料发光性能的影响

The phosphors BaAl12O19:Tb and BaAl12O19:Eu were synthesized by sol-gel method, and the effects of B(superscript 3+) doping on the crystalline structure and luminescent properties of them were studied. The results showed that B(superscript 3+) doping doesn't affect the BaAl12Ol9 structure but improves their luminescent intensity. However, B(superscript 3+) doping plays more obvious role in improving the luminescent intensity of BaAl12O19:Tb than in that of BaAl12O19:Eu and the effective B(superscript 3+) doping dose for the former is obviously greater than that for the latter. The optimum B(superscript 3+) doping doses are 50 mol% and 20 mol% for BaAl12O19:Tb and BaAl12O19:Eu, respectively.
