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2h可合成纯相、表面光滑的Y2O2SO4∶Eu3+亚微米棒,Y2O2SO4∶Eu3+亚微米棒的长度大于10μm,宽度为500～800nm.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％.“,”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 and Eu3+ doping concentration on the crystallography,morphology,and luminescence properties of the samples was investigated.The results show that pure Y2O2SO4∶Eu3+ can be prepared by calcining the raw material mixture at 1100 ℃ for 2 h in air.The monoclinic Y2O2SO4∶Eu3+ (10mol％) sub-micron rods have a length more than 10 μm and a width of 500～800 urn.The photoluminescence spectra of the Y2O2SO4∶Eu3+ sub-micro rods confirm 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 10mol％ was also discussed.
