摘要

采用双坩埚嵌套高温固相法在950 ℃下成功地合成了Ba

ZnS

: Cu荧光粉

探讨了工艺条件和Cu掺杂量对样品发光亮度的影响

用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)和荧光分光光度计分别对其结构、形貌和发光性能进行了表征。结果表明:样品具有单一的Ba

ZnS

晶相结构;与Ba

ZnS

基质不同

该荧光粉的激发光谱在近紫外区存在一个从275~350 nm的宽激发带

归因于Cu发光中心的吸收;该荧光粉在近紫外光激发下发出明亮的黄光

发射中心波长位于560 nm处

是一种良好的黄光材料。

Abstract

Novel Ba

ZnS

: Cu phosphors were successfully prepared by conventional solid reaction via a double-crucible method for the first time. The effect of the technological conditions and Cu doping concentration on luminescent properties of Ba

ZnS

: Cu phosphors was observed. The crystal structure

morphology and photoluminescent properties of the particles were examined

respectively. XRD results indicate that the pure Ba

ZnS

crystal structure was obtained at 950 ℃ for all samples. The Ba

ZnS

: Cu phosphors can excited effectively by 322 nm ultraviolet. The photoluminescence spectra show that the Ba

ZnS

: Cu phosphor emits a yellow light with a broad emission band centered at 560 nm

which was a promising phosphor.
