Abstract

First-principles pseudo-potential approach on complete zinc oxide (ZnO), vacant O (ZnO∶V o ), vacant Zn (ZnO∶V Zn ), interstitial Zn (ZnO∶Zn i ), chloride (Cl) and sulfur (S) co-doped defective ZnO (ZnO∶ClSV Zn , ZnO∶ClSZn i ) reveal that V o is a shallow donor dopant which has nothing to do with green emission. V Zn and Zn i both induce green emission recombination levels in the gap. When Cl and S co-dope in defective ZnO, they will enhance the green emission luminescence intensity, because they can promote the formations of V Zn and Zn i defects.
