摘要:

采用简单的熔盐法合成了KMnF3单相样品及稀土离子铕掺杂的KMnF3(KMnF3:Eu)荧光样品. X射线粉末衍射(XRD)表征结果显示,KMnF3属立方晶系,为AMF3型钙钛矿结构氟化物. 对样品KMnF3:Eu的发光性质进行了研究,荧光光谱分析结果表明,Mn2+,Eu2+与Eu3+这3个发光中心共存于KMnF3:Eu体系中. 讨论了改变掺入Eu离子的摩尔分数对Mn2+,Eu2+以及Eu3+发光强度的影响.

关键词: 氟化物, 熔盐法, 荧光性质

Abstract:

KMnF3 and europium-doped KMnF3(KMnF3:Eu) were prepared via a simple molten salt synthesis(MSS) method and the samples were characterized by X-ray diffraction and photoluminescence spectra. Fluorescence spectrum analysis indicates that three luminescence centers(Mn2+, Eu2+ and Eu3+) coexist in KMnF3:Eu system. By changing the molar fraction of Eu, the luminous intensities of Mn2+, Eu2+ and Eu3+ were further discussed.

Key words: Fluoride, Molten salt synthesis, Luminescence property
