摘　　要：由于ZnO具有大的激子束缚能,有利于在室温下获得高效稳定的紫外辐射。因此,对ZnO激子发光的研究极有希望解决半导体照明、紫外半导体激光器等多种技术面临的瓶颈问题。综述了ZnO中激子的典型光致发光谱、激子的结构及复合发光过程。重点介绍了温度、激发功率、量子限域效应以及激光辐照等因素对ZnO激子发光的影响。It is favourable to obtain the stable and efficient UV irradiation at room temperature due to the high exiton binding energy of ZnO. The research on the excitonic luminescence in ZnO is hopeful to solve the bottleneck problems of the techniques, such as solid state lighting, UV laser diodes. The typical photoluminescence spectra, the exciton structure and the process of recombination luminescence of ZnO exciton are summaried. The influencing factors such as temperature, excitation power, quantum confinement effect and the laser irradiation on excitonic luminescence in zinc oxide are emphasized.
