摘要

采用水热制备系列Ag₂Sr(MoO₄)₂∶xSm³⁺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,Sm³⁺的掺入不影响Ag₂Sr(MoO₄)₂∶xSm³⁺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,Ag₂Sr(MoO₄)₂∶0.08Sm³⁺荧光粉发出更亮的红光,而且具有良好的发光性能。

Abstract

Ag₂Sr(MoO₄)₂∶xSm³⁺ 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 Sm³⁺ did not affect the formation of Ag₂Sr(MoO₄)₂∶xSm³⁺ crystal phase.The crystalline grains were small and uniform distribution.Under the irradiation of ultraviolet lamp,the Ag₂Sr(MoO₄)₂∶0.08Sm³⁺fluorescent powder emited brighter red light,and displayed good luminescent properties.
