Abstract
Single-crystalline ZnO nanorods with an average diameter of 16 nm were fabricated by a simple microemulsion route using dodecyl benzene sulfonic acid sodium (DBS) as a capping agent. Structural characterizations using X-ray diffraction and transmission electron microscopy revealed that the well-dispersed ZnO nanorods have a wurtzite structure with a c-axis growth orientation. Temperature-dependent photoluminescence measurement of the ZnO nanorods has been carried out and the strong excitonic emission and quite weak deep level emission were observed.
