摘要:

 采用溶胶–凝胶燃烧法,在不同柠檬酸用量和热处理温度条件下合成了系列LaBO3:Eu3+发光粉。结果表明:柠檬酸与稀土离子摩尔比为1:1,700 ℃热处理获得单斜结构的LaBO3:Eu3+发光粉。通过提高热处理温度和增加柠檬酸用量获得正交结构的LaBO3:Eu3+发光粉。LaBO3:Eu3+发光粉的形貌受合成条件的影响。单斜结构LaBO3:Eu3+发光粉Eu3+离子的5D0→7F1和5D0→7F2发射峰强度相近;正交结构LaBO3:Eu3+发光粉的主发射峰来自于Eu3+的5D0→7F2跃迁。正交结构发光粉的发光强度高于单斜结构的发光粉。5D0→7F2与5D0→7F1跃迁发射的相对强度比值说明:正交结构的LaBO3:Eu3+中Eu3+局域环境的对称性较低。发光强度和Eu3+局域环境的对称性与柠檬酸用量及热处理温度有关。LaBO3:Eu3+发光粉的Eu3+最佳掺杂量为5%。

 

 A series of LaBO3:Eu3+ phosphors were prepared by a sol-gel combustion method with different amounts of citric acid and annealing temperatures. The results show that LaBO3:Eu3+ phosphors with monoclinic system can be obtained by annealing precursor of molar ratio of citric acid to rare earth ions being 1:1 at 700 ℃. The orthorhombic LaBO3:Eu3+ is obtained when the annealing temperature and the amount of citric acid are increased. The morphology of LaBO3:Eu3+ can be changed under different synthesis conditions. The emission intensity attributed to 5D0→7F2 transitions of Eu3+ is similar to that attributed to 5D0→7F1 transitions for monoclinic LaBO3:Eu3+, and the main emission peaks of orthorhombic LaBO3:Eu3+ originate from 5D0→7F2 transitions of Eu3+. The luminescence intensity of orthorhombic LaBO3:Eu3+ phosphors is more intense than that of monoclinic LaBO3:Eu3+. The 5D0→7F2/5D0→7F1 relative emission intensity ratios show that the local symmetry environment around Eu3+ ions decreases in orthorhombic LaBO3: Eu3+, compared to monoclinic LaBO3:Eu3+. The luminescence intensity and local symmetry environment around Eu3+ ions are related to the amount of citric acid and annealing temperature. The optimal Eu3+ doping amount of LaBO3:Eu3+ phosphors is 5%.
