Abstract

Self-assembled nanorod array (NRA) heterostructures consisting of single-crystalline Er-doped ZnO NRAs on Au island films have been synthesized by a chemical method and proposed as one of the promising optoelectronic materials since the Er intra-4f shell transition leads to 1540 nm emission for optical communication. The microstructural analysis, electronic structure analysis, and photolu- minescence characterizations have been performed. The enhanced 1540 nm emission of Er-doped ZnO NRAs is due to the enhancement of deep level emission of ZnO host, which results from local field enhancement effects of Au island films, and subsequent energy transfer to Er3+.
