The Luminescence Mechanism and the Structure Defects of ZnO Thin Films

Abstract

ZnO will become a new pattern optoelectronic material because of its many excellent properties. But the defects in ZnO crystal are the key factors for restricting the luminescence properties of the material. In this paper, we summarized the defect types that exist in ZnO thin films and reviewed on the relationship between the luminescence mechanism and the structure defects of ZnO thin films reported in recent years.
