摘要：

Negative thermal quenching of both the excitonic and green emissions is observed in ZnO nanosheets, from which the energy level of surface traps can be extracted based on a model of multi-level transitions. The present study demonstrates a nondestructive and easy method to determine the trap levels in semiconductor nanostructures.
