摘　　要：采用水热制备系列Ag_(2)Sr(MoO_(4))_(2)∶xSm^(3+)红色荧光粉,并对其进行X射线衍射、扫描电镜和荧光光谱测试。结果表明,Sm^(3+)的掺入不影响Ag_(2)Sr(MoO_(4))_(2)∶xSm^(3+)晶相的形成,合成的荧光粉体晶粒较小,粒度分布均匀。在紫外灯照射下,Ag_(2)Sr(MoO_(4))_(2)∶0.08Sm^(3+)荧光粉发出更亮的红光,而且具有良好的发光性能。Ag_(2)Sr(MoO_(4))_(2)∶xSm^(3+) red phosphors were synthesized by hydrothermal method and tested by X-ray diffraction(XRD),scanningelectron microscopy(SEM)and fluorescence spectroscopy.The results shown that the incorporation of Sm^(3+)did not affect the formation of Ag_(2)Sr(MoO_(4))_(2)∶xSm^(3+) crystal phase.The crystalline grains were small and uniform distribution.Under the irradiation of ultraviolet lamp,the Ag_(2)Sr(MoO_(4))_(2)∶0.08Sm^(3+) fluorescent powder emited brighter red light,and displayed good luminescent properties.
