|Title:||Mechanism of green luminescence in ZnO|
Lakshmanan, A R
Jose, M T
|Abstract:||ZnO grown under reducing condition is always Zn excess. These Zn atoms are positioned at interstitial sites due to the escape of oxygen from ZnO. The oxygen vacancies created by alkali metal dopants in ZnO play a major role in its green luminescence. This is understood on the basis of charge transfer between Zn interstitials and neighbouring oxygen vacancies caused by the doping of monovalent ions such as Li, Na or K at divalent Zn lattice sites followed by Stokes shifted emission.|
