摘要：

The exciton luminescence of ZnO monocrystals at liquid helium temperature with a picosecond time resolution has been studied. It is shown that the major part of the edge luminescence of ZnO is due to the excitons bound by surface centres. This surface-bound exciton proved to have an unusually short (60 ps) decay time. The Auger process and the radiative recombination are discussed as a possible decay mechanism of these excitons. © 1990.
