Effects of Dopants on the Morphology and Properties of ZnO Nano-assembly System

  • 摘要: 目前, ZnO半导体材料在紫外激光器、气体传感器、场发射晶体管、光电探测器、压电传感器等光电子器件上已得到广泛的应用。但ZnO独特的结构缺陷即自补偿现象, 限制了它在许多光电器件中的使用。本文综述了近年来主族金属离子、过渡金属离子、稀土元素离子等掺杂剂对ZnO纳米组装体系形貌及性能的影响, 并对掺杂剂制备特殊形貌ZnO的发展方向和应用前景进行了展望, 以期为制备性能优越的ZnO纳米材料提供参考。

     

    Abstract: ZnO semiconductor material has been widely used in optoelectronic devices such as ultraviolet lasers, gas sensors, field emission transistors, photodetectors, piezoelectric sensors and so on. However, the unique structural defect of ZnO, namely the self-compensation phenomenon, limits its application in many optoelectronic devices. In this paper, the effects of dopants such as main group metal ions, transition metal ions and rare earth ions on the morphology and properties of ZnO nanoassembly systems are reviewed, and the development direction and application prospects of ZnO with special morphology prepared by dopants are prospected, so as to provide a reference for the preparation of ZnO nanomaterials with superior properties.
