中文摘要:
      以Na2SO4和K2SO4为熔盐,采用熔盐法合成了一维Y2O2SO4:Eu3+亚微米棒。应用X射线衍射、扫描电子显微镜和光谱仪等方法对合成产物的晶体结构、形貌和发光性能进行表征。考察了烧结温度、Eu3+掺杂浓度对合成产物的晶体结构、形貌和发光性能的影响,结果表明,原料混合物在1100℃空气中煅烧2 h可合成纯相、表面光滑的Y2O2SO4: Eu3+亚微米棒,Y2O2SO4: Eu3+亚微米棒的长边大于10 μm,短边为500~800 nm。在270nm紫外光的激发下,Y2O2SO4: Eu3+亚微米棒呈红光发射,最强发射峰位于616 nm处,归属于Eu3+的5D0→7F2跃迁,Y2O2SO4: Eu3+亚微米棒Eu3+的最佳掺杂浓度为10mol%。

英文摘要:
      One-dimensional Y2O2SO4:Eu3+ sub-micron rods were synthesized by a facial molten-salt method with Na2SO4 and K2SO4 as the eutectic melt. The crystallography, morphology and luminescence properties of as-synthesized products were characterized by X-ray powder diffraction (XRD), scanning electronic microscope (SEM) and photoluminescence(PL) spectra.The influence of the sintering temperature, Eu3+ doping concentration on the crystallography, morphology, and luminescence properties of the samples were carefully investigated. The pure Y2O2SO4:Eu3+ can be prepared by calcining raw material mixture at 1100℃ for 2 h in air. The monoclinic Y2O2SO4:Eu3+ (10 mol%) sub-micron rods have a length of more than 10 μm and a width of 500~800 nm. The photoluminescence spectra of the Y2O2SO4:Eu3+ sub-micro rods confirmed the strongest red emission peak at 616 nm upon the excitation of 270 nm ultraviolet light, which corresponds to the 5D0→7F2 transition of Eu3+. Moreover, the quenching concentration mechanism of Y2O2SO4:Eu3+ samples with Eu3+ above 10 mol% was also discussed.
