Eu(OH) with various shape-controlled morphologies and size, such as plate, rod, tube, prism and nanoparticles was successfully synthesized through simple hydrothermal reactions. The products were characterized by XRD (X-Ray Powder Diffraction), FE-SEM (Field Emission- Scanning Electron Microscopy) and TG (Thermogravimetry). The influence of the initial pH value of the starting solution and reaction temperature on the crystalline phase and morphology of the hydrothermal products was investigated. A possible formation process to control morphologies and size of europium products by changing the hydrothermal temperature and initial pH value of the starting solution was proposed.
通过简单的水热反应成功合成了具有各种形状可控形态和尺寸的氢氧化铕，如片状、棒状、管状、棱柱状和纳米颗粒状。产物通过X射线粉末衍射（XRD）、场发射扫描电子显微镜（FE-SEM）和热重分析（TG）进行表征。研究了起始溶液的初始pH值和反应温度对水热产物晶相和形态的影响。提出了一种通过改变水热温度和起始溶液的初始pH值来控制铕产物形态和尺寸的可能形成过程。
