title: ZnO coaxial nanorod Homojunction UV light-emitting diodes prepared by aqueous solution method.
abstract: The fabrication of a p-shell/n-core coaxial nanorod ZnO homojunction light-emitting diode by inexpensive solution method is demonstrated. The p-type conductivity of the ZnO shell arises from the incorporation of potassium while the n-type conductivity of the core is due to unintentional doping.
