Keywords:ZnO, photoluminescence, Intrinsic donor

While electric conduction of transparent conductive ZnO films originates from intrinsic donors related to defects, it has not been established which kind of donors actually contribute. On the other hand, photoluminescence from deep levels provides information about electronic transition between defects and conduction/valence bands. However, there are only few works studying correlation between electric conduction and photoluminescence. We attempted to present one-to-one correspondence between electric condution and photoluminescence properties.
