摘　　要：采用简单的水热法合成了Dy(OH)_3纳米棒和纳米带,通过SEM、TEM、EDS和XRD等手段对产物进行了表征。研究了pH值和水热温度对Dy(OH)_3纳米晶形貌的影响。实验发现,调节水热温度可以控制Dy(OH)_3纳米棒的形貌,而Dy(OH)_3纳米带的形成与pH值密切相关。这为合成其它稀土化合物一维纳米材料提供了一个新的途径。Dy（OH）3 nanorods and nanobelts were fabricated by facile hydrothermal method. The properties of products were characterized by SEM, TEM, XRD and EDX. Effects ofpH value and hydrothermal temperature on the morphologies of Dy（OH）3 nanocrystals were also investigated. In the process, the temperature were found to play important roles in determining morphologies Dy（OH）3 nanorods, and pH value also plays an important role in synthesizing the Dy（OH）3 nanobelts. The 1D nanostructure growth method presented herein offers a new tool for synthesizing other rare earth compounds.
