摘要

采用固相法合成了KSr

(BO

)

(KSB:

)荧光粉

通过X射线粉末衍射(XRD)、扫描电镜(SEM)及光致发光光谱分别研究了样品的晶相、形貌及发光性质.XRD研究结果表明制备的样品为正交晶系的KSr

(BO

)

单相.当Eu

的掺杂摩尔分数

为1.5%时

在激发光谱250~550 nm范围内观察到了两个宽带激发

可归属为Eu

的4f

-4f

跃迁;在400 nm激发下

发射谱呈现出一个不对称的黄色发射带

峰值位于560 nm处

可归属于Eu

的4f

-4f

跃迁.因在KSr

(BO

)

化合物中存在3个Sr格位

根据其光谱特征可推测发射谱中非对称的发射带来源于多个Eu

发光中心.

Abstract

KSr

(BO

)

(KSB:

) phosphors were synthesized by solid-state reaction method. The phase

morphology

and luminescence properties of the samples were characterized by using XRD

SEM

and photoluminescence spectra. XRD results show that the as-prepared samples are orthorhombic KSr

(BO

)

single-phase. When

=1.5%

two broad bands are observed from 250 to 550 nm in the excitation spectra

which are attributed to 4f

-4f

transition of Eu

. Under the excitation of 400 nm

the emission spectrum shows an asymmetric yellow emission band around 560 nm

attributed to 4f

-4f

transition of Eu

. Because of three Sr crystallographic sites in KSr

(BO

)

compound

one can infer that the asymmetric emission results from multiple Eu

centers by the spectral characteristics.
