Abstract：Due to the wide direct bandgap（3.37eV），large exciton binding energy（60 meV）and excellent optical gain characteristics，zinc oxide（ZnO） becomes an idealmaterial forlow-dimensionaland eficient ultraviolet light-emitting and laser devices.Recently，lasing actions have been widely observed in various ZnO microcavitiesunderoptical excitation，butthe developmentofelectricallypumped devices is thekey totheir practical application.This review starts withabrief overview of the basic properties of ZnOand common fabrication methodsfor itsmicro-/nanostructures，then therecent progresses of light-emitting and laserdevices based on ZnO micro-/nanostructures were discussed according to different device architectures.Initially，this review focuses on the progresses of light-emitingand laser devicesbased on low-dimensional ZnO heterostructures and Schottky structures，alongside the methodologies for the performance optimization.Subsequently，itdelves into thecurrent landscape of research pertaining to p-type ZnO materialsand their homostructural counterparts in light-emitting and laserapplications.Finall，the remaining issues and future development directions of ZnObased devices have been summarized.
