摘要

采用层层浸渍法制备石英玻璃基铕离子(Eu³⁺)∶钨酸钇钾[KY(WO₄)₂][(Eu³⁺)∶KY(WO₄)₂]薄膜。通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)、荧光光谱仪和原子力显微镜进行表征。结果表明:薄膜由Eu³⁺∶KY(WO₄)₂单斜晶体组成,薄膜表面粗糙度Ra=22.343nm,在262nm激发光下可发射614nm(Eu³⁺离子 ⁵D₀→⁷F₂跃迁)的红光,其中262nm处为钨酸根离子中的O→W的电荷转移而产生的光波段,说明WO^2-₄子与Eu³⁺之间存在能量传递,614nm处的荧光寿命是0.98ms。

Abstract

Eu³⁺∶KY(WO₄)₂ films on silica glass substrate were prepared through the pechini sol-gel system with the layer-by-layer dipping technology.X-ray diffraction (XRD),scanning electron microscope (SEM),microscopic probe microscope,photoluminescence excitation and emission spectra as well as decay curve were used to characterize the films.The results indicated that the films consist of Eu³⁺∶KY(WO₄)₂ monoclinic structure,the surface roughness of film was 22.343nm.The broad excitation band with maximum at 614nm was ascribed to absorption of WO^2-₄ for the charge-transfer from WO^2-₄ group of the host material to Eu³⁺ ions.The films emitted red light centered at 614nm under the excitation of 262nm,and the photoluminescence lifetime was 0.98ms.
