摘　　要：研究了Mg,La,Ce掺杂对BaAl12O19∶Mn晶体结构和发光性能的影响。晶体结构的研究结果发现:La,Ce取代了部分Ba的晶格位置,Mg和Mn取代了部分Al的晶格位置,Ce和La对Ba的取代使得BaAl12O19∶Mn晶胞体积减小,Mg的掺杂使得BaAl12O19∶Mn晶胞体积增大。发光性能的测试结果表明,在一定的浓度范围内,Mg,La,Ce都有效地提高了BaAl12O19:Mn在真空紫外下的发光强度。The effect of Mg,Ce-doping on crystal structure and luminescence of the BaAl12O19:Mn phosphor was studied in this paper . The XRD results show that La and Ce substitute for part of the Ba,while Mg and Mn substitute part of the Al.The lattice parameters of BaAl12O19:Mn become smaller after substitution of La and Ce,while the doping of Mg and Mn makes the lattice volume become larger.luminescent properties results show that in the appropriate concentration range the doping of Mg,La and Ce can increase the luminescent intensity of BaAl12O19:Mn in the VUV.
