氧化锌(ZnO)是Ⅱ–Ⅵ族直接宽禁带半导体材料,有望在光电显示、光电存储、光电转化和紫外光电探测等领域得到广泛应用。然而,如何制备稳定的p型ZnO是其应用和发展的瓶颈。目前,在众多制备p型ZnO的方法中,尽管溶液法制备p型ZnO的报道不多,但溶液法是一种成本廉价、操作简易、环境友好的制备p型ZnO的方法。综述了目前通过非掺杂、Ⅰ族元素掺杂、Ⅴ族元素掺杂、给体–受体共掺杂的溶液方法制备p型ZnO及其光电器件的研究进展,分析了现阶段溶液法制备p型ZnO的优点和不足之处。
ZnO is aⅡ–Ⅵ group semiconductor material with the wide direct band gap,and is expected to be widely used in the optical display,optical storage,photoelectric conversion,ultraviolet detection and other fields.However,how to achieve a stable p-type ZnO is one of challenges for its application and development.Among the existing methods for the preparation of the p-type ZnO,a solution method has its own advantages such as low cost,simple operation and environment-friendly although there are a few reports about p-type ZnO prepared by the solution method.The paper reviews the development of the p-type ZnO synthesized by the solution method(i.e.,non-doping,Ⅰgroup elements doping,Ⅴgroup elements doping,donor–acceptor co-doping) and optoelectronic devices research.The advantages and disadvantages of the p-type ZnO synthesized by the solution method were discussed.
