摘　　要：氧化锌(ZnO)拥有较宽的直接带隙(3.37 eV)、可观的激子束缚能(60 meV)以及良好的增益特性,这使其成为低维高效纯紫外发光及激光器件的理想材料。目前,基于各种形态的ZnO微腔已经实现了光泵浦激光,但电驱动器件的开发才是其走向实际应用的关键。本文简要回顾了ZnO的基本特性及其微纳结构的常见制备方式,按不同的器件结构梳理了基于ZnO微纳结构的发光和激光器件的主要研究进展。首先,阐述了基于低维ZnO异质结构和肖特基结构的发光与激光器件及相应性能优化手段的研究进展;进一步讨论了p型ZnO材料及相应同质结构发光与激光器件的研究现状;最后对ZnO基器件仍旧存在的问题和未来发展方向进行了总结与展望。Due to the wide direct bandgap(3.37 eV),large exciton binding energy(60 meV)and excellent optical gain characteristics,zinc oxide(ZnO)becomes an ideal material for low-dimensional and efficient ultraviolet light-emitting and laser devices.Recently,lasing actions have been widely observed in various ZnO microcavities under optical excitation,but the development of electrically pumped devices is the key to their practical application.This review starts with a brief overview of the basic properties of ZnO and common fabrication methods for its micro-/nanostructures,then the recent progresses of light-emitting and laser devices based on ZnO micro-/nanostructures were discussed according to different device architectures.Initially,this review focuses on the progresses of light-emitting and laser devices based on low-dimensional ZnO heterostructures and Schottky structures,alongside the methodologies for the performance optimization.Subsequently,it delves into the current landscape of research pertaining to p-type ZnO materials and their homostructural counterparts in light-emitting and laser applications.Finally,the remaining issues and future development directions of ZnObased devices have been summarized.
