    Effect of Different Ce3+/Tb3+-doping Concentration on Fluorescent Properties of LaPO4:Ce3+/Tb3+Crystals

      摘要
    • 摘要:用溶剂热法、150 ℃反应12 h成功合成了分散性良好的LaP0 4:Ce 3+/Tb 3+荧光晶体.XRD数据表明,合成了六方晶系的LaP0 4:Ce 3+/Tb 3+晶体(PDF 84-0600).pH为9.0时,合成晶体的离子最佳摩尔比为 nLa 3+: nCe 3 +:nTb 3+=6:3:1.根据荧光光谱可知,LaP0 4:Ce 3+/Tb 3+在270 nm处有最强激发峰,在545 nm处有最强发射峰,对应于Tb 3+的 5D 4→ 7F 5跃迁

      Abstract:LaPO 4:Ce 3+/Tb 3+fluorescent crystals were successfully synthesized by solvothermal method at 150 ℃ for 12 h. The statistics of XRD showed that the LaP0 4:Ce 3+/Tb 3+(PDF 84-0600)Crystals thus prepared are of a hexagonal system. The optimal molar ratio of the composite particles is nLa 3+:nCe 3+:nTb 3+=6:3:1 when the pH of the solution was 9.0. By means of fluorescence spectra, it is easy to find that the strongest excitation peak for LaP0 4:Ce 3+/Tb 3+appears at 270 nm, and the strongest emission peak is found at 545nm which corresponds to the 5D4→7F5 transition of Tb 3+
