稀土掺杂ZnO纳米材料的合成方法研究进展

摘要

Rare-earth( RE )ions doped ZnO semiconductors have become the focus of numerous investigations because of their unique optical properties and promising applications in optoelectronic devices. The bandgap structure of ZnO will be modulated substantially and the free carrier concentration in ZnO will also be changed with the RE ion doping. So research the simple and easy synthetic methods have been the hot topic. In this paper, some synthetic methods of RE-doped ZnO nanomaterials are introduced,and the related results are also given. This work will be benefit for the further research of RE-doped ZnO nanomaterials.%稀土掺杂ZnO材料可以引起ZnO的能带结构和载流子浓度的改变，同时利用稀土离子的4f-4f跃迁和半导体材料的独特性能对材料的光学性质进行调制，可以使稀土掺杂ZnO具有不同于本征ZnO的新特性。因此，研究其简单、可行的合成方法成为人们研究的热点，这也是研究材料性能的前提条件。本文主要介绍了稀土掺杂ZnO纳米材料的几种合成方法，并且给出了不同合成方法制备稀土掺杂ZnO纳米材料的部分实验结果。通过对稀土掺杂ZnO纳米材料体系的合成方法研究的分析和论述，希望对该类材料的进一步研究工作有所帮助和启发。
