The structural and optical properties of post surface Eu-treated ZnO nanowires (NWs) have been investigated systematically. It is found that the Eu3+ ions are in the Eu2O3-like state located at the surface of ZnO NWs. Sharp intense red emissions in the range of 580−650 nm due to the intra-4f transit...
