纳米氧化锌薄膜蓝光发射机制的研究进展

氧化锌是一种重要的短波长光电子材料。除了它的紫外发射之外，氧化锌的蓝光发射也同样引起了人们的极大关注。尽管人们已经对ZnO材料的蓝光发射做了比较深入的研究，然而对于它的发射机理目前尚无统一的结论。从理论和实验两方面对氧化锌薄膜的蓝光发射机制进行了综述，重点介绍了由锌填隙、锌空位、氧空位及杂质导致的缺陷发光模型。根据上面的分析及实验研究结果，认为蓝光发射主要与锌间隙和锌空位缺陷有关。

Advance in Research on the Blue Emission Mechanism of Nanocrystalline ZnO Films

Zinc oxide is an important short-wavelength optoelectronics material.Besides its UV emission,the blue emission of ZnO has also attracted widespread attention and many deep researches have been done,however,its emission mechanism is still hard to draw a unified conclusion.In this paper,the blue emission mechanism of zinc oxide thin films has been reviewed from theoretical and experimental research.Especially on the Luminescence model originating from defect such as,the zinc vacancies,the oxygen vacancy and t...
