通过水热的方法制备了EuOOH和Eu2O3混合物。采用X-射线衍射、能量弥散型X-射线谱和扫描电镜技术表征产物的晶体结构、组成和形貌。实验表明,通过控制条件水热温度和反应时间可控制产物的形貌和尺寸。产物的最大激发波长位于204 nm处,于592和617 nm处有较强的荧光发射,且其发射强度和激发强度皆随制备温度的增加而增加。

A mixture of EuOOH and Eu2O3 was synthesized through hydrothermal method.The structure,component and morphology of the as-prepared products were characterized by the techniques of powder X-ray diffraction（XRD）,energy-dispersive X-ray spectrum（EDS） and scanning electron microscopy（SEM）.Experimental results showed that the morphology and size of the as-prepared products could be controlled by adjusting the reaction temperature and time.The maxmum exciting wavelength of the products was at about 214 nm,and the emition wavelengthes were at about 592 and 617 nm,respectivelly.The relative intensity of the exciting and emission peaks were all enhanced with the increasing of reaction temperature.
