説明:

Low dimensional ZnO-based materials have drawn much attention for the past decades due to their unique electronic and optical properties and potential applications in optoelectronic devices. In this tutorial, we will cover the past and the latest developments in ZnO thin films and micro/nanostructures in terms of excitonic and related lasing processes. First, we will give a brief overview of temperature-dependent linear excitonic absorption and luminescence spectra. Second, we will introduce feedback mechanism for lasing in various forms of ZnO, ranging from nanoparticles to nanowires, nanodisks and thin films. As for the feedback mechanism, detailed descriptions are given to random lasing, Fabry-Perót lasing, and whispering gallery mode lasing. Third, we discuss possible gain mechanisms, i.e., excitonic gain and electron-hole plasma (EHP) gain, in ZnO. A special interest is also devoted to the Mott carrier density, which is a crucial parameter to distinguish between excitonic and EHP contributions to lasing.
