Abstract
High-quality well-aligned ZnO and Zn1-xMgxO nanorods were grown on Si(001) substrates by using metalorganic chemical vapor deposition. The temperature dependent and polarized behavior of photoluminescence observed in well-aligned ZnO and Zn1-xMgxO nanorods in the temperature range of 25-295k is described. luminescence was dominated by localized excitons LX1 and LX2 in Zn1-xMgxO nanorods. With increasing Mg content LX2 became dominated the luminescence in low temperature. And increasing Mg content also influenced the luminescence to be boarding. It is found that both ZnO and Zn1-xMgxO nanorods were strongly polarized along the long axis. This indicated that ZnO and Zn1-xMgxO nanorods had high optical quality and with changing Mg content we can control deferent energies emissions with strongly polarized.
