摘要

以黄磷炉渣为硅源,采用表面修饰法制备得到稀土配合物Eu(EDTA)-掺杂的SiO2荧光材料。通过X射线衍射(XRD)、扫描电子显微镜(SEM)和荧光光谱(PL)等表征方式对产物结构、形貌以及发光性进行了表征。结果表明:所合成的SiO2∶Eu3+荧光粉为无定型结构,可被近紫外光(395nm)有效激发,其发射主峰位于616nm处,归属于Eu3+5D07F2电偶极跃迁。SiO2∶Eu3+样品形貌为块状颗粒,清晰可见有大量小颗粒聚集在大颗粒的表面。

Abstract

Yellow phosphorus slag used as the silicon source,the earth complex Eu(EDTA)-doped SiO2 fluorescent materials were prepared by surface modification.The structure,morphology and luminescence of the product were characterized by X-ray diffraction (XRD),scanning electron microscope (SEM) and fluorescence spectroscopy (PL).The results shown that the synthesized SiO2∶ Eu3+ phosphor had an amorphous structure,and can be effectively excited by near ultraviolet light (395nm).Its main emission peak was at 616nm,which was belong to the 5D07F2 electric dipole transition of Eu3+.The morphology of the SiO2∶Eu3+ sample was massive particles.It can be clearly seen that a large number of small particles were gathered on the surface of the large particles.
