摘要

采用水热法制备了Eu

掺杂的-Ga

粉体

利用X射线粉末衍射、场发射扫描电子显微镜、透射电子显微镜、拉曼光谱和发光光谱等测试手段对其物相、形貌和发光性能等进行了研究。结果表明:所得样品为单斜晶系的-Ga

;在波长为325 nm的He-Cd激光器激发下

发射光谱的最强峰位于612 nm

属于Eu

的

电偶极跃迁;在模拟太阳光照射下

样品对甲基橙具有较高的光催化降解率

经过2 h后

甲基橙的降解率可达到75%。

Abstract

doped -Ga

powders were prepared by hydrothermal method. X-ray diffraction

field emission scanning electron microscopy

transmission electron microscopy

Raman spectroscopy

and photoluminescence spectra were used to characterize the structure and properties of -Ga

: Eu

powders. The results reveal that the obtained samples are monoclinic -Ga

powders. Under the excitation of 325 nm He-Cd laser

the strongest emission peak is located at 612 nm

corresponding to the

transition of Eu

. -Ga

:Eu

powders have high photocatalytic degradation rate for methyl orange under simulated solar irradiation

and the photocatalytic degradation rate of methyl orange is up to 75% after 2 h degradation.
